US gun lobby urges armed police in every school






WASHINGTON: The US' most powerful pro-gun lobbying group is suggesting that armed police be deployed to every school in the country following a mass shooting that left 20 young children dead.

The National Rifle Association, which supports a broad interpretation of US citizens' constitutional right to bear arms, had been under pressure to respond in the wake of last week's massacre in a Connecticut elementary school.

Even as the NRA leaders made their combative and determined appearance, another four people died in Pennsylvania in America's latest shooting spree, including the alleged shooter.

And a string of celebrities including Jeremy Renner, Gwyneth Paltrow and Beyonce launched a video to back a campaign to clamp down on gun sales following the Newtown school massacre.

But the pro-gun lobbyists ceded no ground to those calling for tougher gun laws.

"The only thing that stops a bad guy with a gun is a good guy with a gun," declared NRA vice-president Wayne LaPierre Friday, in his first public comments since the shooting at the Sandy Hook Elementary School in Newtown, Connecticut.

"I call on Congress today to act immediately to appropriate whatever is necessary to put armed police officers in every single school in this nation," he said, in a lengthy statement. He took no questions from reporters.

LaPierre said the NRA was ready to help train security teams for schools and work with teachers and parents to improve security measures, and accused the media and the political class of demonising gun owners.

Last Friday, a troubled 20-year-old man burst into the Sandy Hook school and gunned down 20 six- and seven-year-old children and six staff members trying to protect them, before taking his own life. He also fatally shot his mother.

As LaPierre and his allies were on stage in Washington on Feiday, police in Pennsylvania shot dead a man who had killed three people and wounded "several" others, state troopers.

These deaths were the latest in a series of mass shootings in the United States this year, and prompted President Barack Obama to throw his weight behind plans to revive a ban on assault weapons.

America has suffered an epidemic of gun violence over the last three decades including 62 mass shooting incidents since 1982. The vast majority of weapons used have been semi-automatic weapons obtained legally by the killers.

There were an estimated 310 million non-military firearms in the United States in 2009, roughly one per citizen, and people in America are 20 times more likely to be killed by a gun than someone in another developed country.

But LaPierre insisted gun ownership is not the problem.

"You know, five years ago after the Virginia Tech tragedy when I said we should put armed security in every school, the media called me crazy," he said, referring to a 2007 campus shooting that left 32 people dead.

"But what if, what if when Adam Lanza started shooting his way into Sandy Hook Elementary School last Friday, he'd been confronted by qualified armed security?" he demanded.

"Will you at least admit it's possible... that 26 innocent lives might have been spared that day? Is it so abhorrent to you that you'd rather continue to risk the alternative?"

The statement immediately drew criticism from supporters of tougher gun control, who are pushing to ban semi-automatic assault weapons like the .223 Bushmaster rifle that Lanza used in Friday's shooting.

"The NRA leadership's drive to fill our schools with more deadly guns and ammo is wildly out of touch with responsible gun owners and the American public," New Jersey Senator Frank Lautenberg said.

The New York Times, in an editorial Saturday, did not mince words, calling LaPierre's remarks a "mendacious, delusional, almost deranged rant".

One of the protesters, who attempted to drown out LaPierre's statement, bore a banner reading "NRA kills our kids" the other "NRA has blood on its hands". They were led away by security.

Hollywood stars including Julianne Moore, Jamie Foxx and Jon Hamm meanwhile recorded a video backing a campaign calling notably for a ban on assault weapons, as well as criminal background checks for every gun sold.

"Columbine. Virginia Tech. Tucson. Aurora. Fort Hood. Oak Creek. Newtown. Newtown. Newtown," they intoned in the black-and-white video, taking turns to list the names of America's worst gun massacres of recent years.

"How many more? How many more colleges? How many more classes? How many more movie theatres? How many more houses of faith? How many more shopping malls?" they added in the video on the "Demand a Plan" campaign website.

Obama: Get short-term fix to fiscal cliff, then broader deal






STORY HIGHLIGHTS


  • NEW: President Obama spoke with congressional leaders about a possible deal

  • A Democratic source lays out possible scenarios

  • House Republicans reject Speaker Boehner's tax alternative

  • Everyone's taxes go up in 11 days without an agreement




Washington (CNN) -- President Barack Obama spoke separately Friday with Speaker John Boehner and the top Senate Democrat to try to salvage a fiscal cliff deal by the end of year, after Republican disarray in the U.S. House put the negotiations in limbo.


In a previously unscheduled statement to reporters, Obama outlined a possible agreement that he said would include protecting middle-class Americans from a tax hike, extending unemployment benefits and setting a framework for future deficit reduction steps.


He called on Congress to pass the agreement after a Christmas break so he can sign it before the end of the year, when the fiscal cliff arrives in the form of automatic tax increases and deep spending cuts.


"Laws can only pass with support from Democrats and Republicans," Obama said in urging both sides to compromise.










The president planned to fly with his family to Hawaii on Friday night for the holiday and return to Washington after Christmas, while House and Senate members also headed home with plans to return on December 27 if needed.


Boehner's spokesman said the speaker will be "ready to find a solution that can pass both houses of Congress" when he returns to Washington.


While congressional leaders continued to bicker Friday over the next step, the president's phone discussion with Boehner and a White House meeting with Senate Majority Leader Harry Reid signaled an attempt to provide the nation and investors with hope that an agreement can be reached.


An aide to Reid said the short-term proposal to avoid the fiscal cliff should include extending tax cuts for middle-class families and unemployment insurance while delaying the automatic spending cuts set to take effect in the new year.


Obama acknowledged what had become obvious: the broader deficit reduction deal he seeks will likely come in stages, rather than in the so-called grand bargain he and Boehner have been negotiating.


The main issue of disagreement continued to be taxes, specifically whether rates should go up on top income brackets for the wealthiest Americans as part of an agreement to reduce the nation's chronic federal deficits and debt.


Without a deal, the fiscal cliff could trigger a recession, economists warn. Stocks closed down sharply on Friday over the latest impasse in the deficit talks, a sign of investor fears of a slowdown as the nation slowly continued to emerge from recession.


Earlier Friday, Reid called for House Republicans to quickly approve a Senate plan championed by Obama that would extend tax cuts for family income up to $250,000 while allowing rates to return to higher levels of the 1990s above that threshold.


His Republican counterpart, Sen. Mitch McConnell of Kentucky, responded that the Senate should instead take up a House Republican measure extending the tax cuts for everyone as a temporary move before negotiations next year on broader tax reform.


The GOP revulsion over any kind of tax rate increase has stymied deficit negotiations for two years and led to unusual political drama, such as McConnell recently filibustering his own proposal and Thursday night's rebuff by House Republicans of an alternative tax plan pushed by Boehner, their leader.


Boehner said at a news conference Friday that his Republican colleagues refused to back his plan, which would have extended all tax cuts except for income over $1 million, because of fears of being blamed for a tax increase.


"They weren't taking it out on me," he said. "They were dealing with the perception that somebody might accuse them of raising taxes."


The lack of backing by his own caucus was a political blow to Boehner and raised more questions than answers about what happens next in the tough negotiations with Obama on either a broad deficit reduction agreement or a smaller step to avoid the fiscal cliff.


A breakdown of Boehner's miscalculation on Plan B


A senior Democratic Senate source said scenarios under consideration by the party include trying to work out short-term or comprehensive agreements now, or going into next year -- and over the fiscal cliff -- without a deal to quickly pass a compromise plan in the new Congress that convenes on January 3.


Waiting until next year would make the vote a tax cut from the automatic higher rates that will take effect under the fiscal cliff, instead of the current situation of extending some cuts and having top rates go up, the source noted.


In addition, Democrats will have two more seats in the new Senate and a stronger House minority, as well as increased pressure on Republicans to keep taxes low on middle class Americans, according to the source.


Trying to hammer out a deal now means working with limited time and stronger Republican contingents in both chambers, the source said.


Boehner made clear Friday that the negotiations with Obama on a broad deficit reduction agreement hit an impasse this week when both sides offered their "bottom line" positions that included major concessions -- but remained a few hundred billion dollars apart.


With his alternative plan torpedoed by his own party, Boehner said it now is time for Obama and Senate Democrats to come up with a solution.


Boehner also denied a reporter's suggestion that he is walking away from further talks, but he offered no timetable or mechanism for resuming discussions.


In the Senate, Reid said all House measures on the fiscal cliff so far have failed to meet the minimum demands of Obama, such as wealthy Americans paying more to prevent an increased burden on middle-class families.


"I like John Boehner, but gee whiz, this is a pretty big political battering that he has taken," Reid said, calling on the speaker to allow a vote on the Senate-passed Obama plan. "It will pass. Democrats will vote for it. Some Republicans will vote for it. That is what we are supposed to do."


On Thursday night, the House passed a measure that would reduce the impact of the fiscal cliff's automatic spending cuts on the military.


However, the chamber then went into recess when it was clear Boehner lacked the votes for his separate tax plan that maintained cut rates on income up to $1 million.


Conservatives opposed to any kind of increase in tax rates refused to sign on, and with Democrats unified in their opposition, the measure had no chance of passing.


Fallout from fiscal cliff inaction


"There was a perception created that that vote last night was going to increase taxes. I disagree with that characterization," Boehner said Friday by way of explanation, adding that "the perception was out there, and a lot of our members did not want to have to deal with it."


Reid had said the Senate would spurn the Boehner plan if it passed the House, and Obama promised to veto it if it reached his desk. According to Republican sources, the zero chance for Boehner's Plan B to actually become law influenced some wavering House members to reject it.


Obama campaigned for re-election on extending the tax cuts that date back to his predecessor's administration on income up to $250,000 for families, but returning to higher rates on amounts above that threshold.


Some House Republicans have said they would join Democrats in supporting the president's proposal in hopes of moving past the volatile issue to focus on the spending cuts and entitlement reforms they seek.


The Plan B was significant because Republican leaders previously insisted they wouldn't raise rates on anyone.


Boehner had complained Thursday that in making that concession, he expected but never got significant concessions from Obama.


He elaborated on the negotiations Friday, saying he told Obama that his latest proposal made over the weekend was his bottom line. Boehner said Obama told him the White House counterproposal Monday was the president's bottom line.


Boehner also repeated his complaint that Obama and Democrats were unwilling to address the spending cuts and entitlement reforms that he considers necessary to properly address the nation's chronic federal deficits and debt.


"What the president has proposed so far simply won't do anything to solve our spending problems," Boehner said, noting that "because of the political divide in the country, because of the divide here in Washington, trying to bridge these differences has been difficult."


CNN Poll: Are GOP policies too extreme?


In his statement Friday, Obama said he had compromised at least halfway on major issues, and that both sides have to accept they will not get all they want.


The possibility of a fiscal cliff was set in motion over the past two years as a way to force action on mounting government debt.


Now legislators risk looking politically cynical by seeking to weaken the measures enacted to try to force them to confront tough questions regarding deficit reduction, such as reforms to popular entitlement programs such as Social Security, Medicare and Medicaid.


Polling has consistently shown most Americans back the president, who insists wealthy Americans must pay more, rather than Boehner and his Republican colleagues, who have balked at tax rate hikes and demanded spending cuts and entitlement program reforms.


A new CNN/ORC International survey released Thursday showed that just over half of respondents believe Republicans should give up more in any solution and consider the party's policies too extreme.


Opinion: Boehner leading GOP to the apocalypse


The two sides seemingly had made progress earlier this week on forging a $2 trillion deficit reduction deal that included new revenue sought by Obama and spending cuts and entitlement changes desired by Boehner.


The president's latest offer set $400,000 as the income threshold for a tax rate increase, up from his original plan of $250,000. It also included a new formula for the consumer price index applied to some entitlement benefits, much to the chagrin of liberals.


Called chained CPI, the new formula includes assumptions on consumer habits in response to rising prices, such as seeking cheaper alternatives, and would result in smaller benefit increases in future years.


Statistics supplied by opponents say the change would mean Social Security recipients would get $6,000 less in benefits over the first 15 years of chained CPI.


Liberal groups sought to mount a pressure campaign against including the chained CPI after news emerged this week that Obama was willing to include it, calling the plan a betrayal of senior citizens who had contributed throughout their lives for their benefits.


Poll: Americans view economy as poor, split on future

NRA: Guns in schools would protect students

Updated: 6:44 p.m. ET

In a press conference reflecting on last week's massacre in Newtown, Conn., the National Rifle Association's Wayne LaPierre today called on Congress to put armed law enforcement agents in every American school, insisting that guns in schools -- not tougher gun laws -- would most effectively protect children from school shootings.

A "good guy with a gun" in every school?



LaPierre, who did not take any questions and whose remarks were interrupted twice by pro-gun control protesters, disdained the notion that stricter gun laws could have prevented "monsters" like Adam Lanza from committing mass shootings, and wondered why students, unlike banks, don't have the protection of armed officials. He also called for a "national database of the mentally ill."

"The only thing that stops a bad guy with a gun is a good guy with a gun," he said.

Twenty first-grade students were gunned down at their Connecticut elementary school last Friday, when 20-year-old Lanza reportedly opened fire in the school. Six adult faculty members were killed in his rampage, and Lanza also took his own life. Shortly before entering Sandy Hook Elementary School, Lanza is believed to have killed his mother, Nancy Lanza, in her bed. In the aftermath of the shootings, there has been much speculation as to the state of Adam Lanza's mental health, but no concrete evidence has been established that he was mentally ill.

In the aftermath of the shooting, the NRA stayed largely silent, making only a brief comment earlier this week when announcing today's press conference. In his remarks today, however, LaPierre vehemently defended the pro-gun agency against critics and offered up a solution of his own.

"We must speak for the safety of our nation's children," said LaPierre. "We care about our money, so we protect our banks with armed guards. American airports, office buildings, power plants, courthouses, even sports stadiums, are all protected by armed security. We care about our president, so we protect him with armed Secret Service agents. Members of Congress works in offices surrounded by Capitol police officers, yet when it comes to our most beloved innocent and vulnerable members of the American family -- our children -- we as a society leave them every day utterly defenseless. And the monsters and the predators of the world know it and exploit it."

"That must change now," argued LaPierre, moments before being interrupted by a protester carrying a large pink sign proclaiming that the "NRA is killing our kids." "The truth is that our society is populated by an unknown number of genuine monsters -- people so deranged, so evil, so possessed by voices and driven by demons that no sane person can possibly ever comprehend them. They walk among us every day. And does anybody really believe that the next Adam Lanza isn't planning his attack on a school he's already identified at this very moment?"

Alternately criticizing politicians, the media, and the entertainment industry, LaPierre argued that "the press and political class here in Washington [are] so consumed by fear and hatred of the NRA and America's gun owners" that they overlook what he claims is the real solution to the nation's recent surge in mass shootings -- and what, he said, could have saved lives last week.


"What if, when Adam Lanza started shooting his way into Sandy Hook Elementary School last Friday, he had been confronted by qualified, armed security?" he asked. "Will you at least admit it's possible that 26 innocent lives might have been spared? Is that so abhorrent to you that you would rather continue to risk the alternative?"


LaPierre called on Congress to put a police officer in every school in America, which according to a Slate analysis would cost the nation at least $5.4 billion. LaPierre recognized that local budgets are "strained," but urged lawmakers "to act immediately, to appropriate whatever is necessary to put armed police officers in every school." He offered up the NRA's unique "knowledge, dedication, and resources" to assist in efforts to train those forces, but made no mention of a fiscal contribution. 

Columbine High School employed an armed guard, Neil Gardner, at the time of the 1999 school shootings. According to CNN, Gardner was eating lunch in his car when violence broke out in the school, and 13 people were killed.

Protesters disrupt NRA press conference



Gun control advocates immediately decried LaPierre's comments, and New York City Mayor Michael Bloomberg called the press conference a "shameful evasion of the crisis facing our country."

"Instead of offering solutions to a problem they have helped create, they offered a paranoid, dystopian vision of a more dangerous and violent America where everyone is armed and no place is safe," he said. "Leadership is about taking responsibility, especially in times of crisis. Today the NRA's lobbyists blamed everyone but themselves for the crisis of gun violence."

On Twitter, Senator-elect Chris Murphy, D-Ct., called LaPierre's comments "the most revolting, tone-deaf statement I've ever seen."

Obama Still an 'Optimist' on Cliff Deal


gty barack obama ll 121221 wblog With Washington on Holiday, President Obama Still Optimist on Cliff Deal

Mandel Ngan/AFP/Getty Images


WASHINGTON D.C. – Ten days remain before the mandatory spending cuts and tax increases known as the “fiscal cliff” take effect, but President Obama said he is still a “hopeless optimist” that a federal budget deal can be reached before the year-end deadline that economists agree might plunge the country back into recession.


“Even though Democrats and Republicans are arguing about whether those rates should go up for the wealthiest individuals, all of us – every single one of us -agrees that tax rates shouldn’t go up for the other 98 percent of Americans, which includes 97 percent of small businesses,” he said.


He added that there was “no reason” not to move forward on that aspect, and that it was “within our capacity” to resolve.


The question of whether to raise taxes on incomes over $250,000 remains at an impasse, but is only one element of nuanced legislative wrangling that has left the parties at odds.


For ABC News’ breakdown of the rhetoric versus the reality, click here.


At the White House news conference this evening, the president confirmed he had spoken today to Senate Majority Leader Harry Reid, D-Nev., and House Speaker John Boehner, R-Ohio, although no details of the conversations were disclosed.


The talks came the same day Speaker Boehner admitted “God only knows” the solution to the gridlock, and a day after mounting pressure from within his own Republican Party forced him to pull his alternative proposal from a prospective House vote. That proposal, ”Plan B,” called for extending current tax rates for Americans making up to $1 million a year, a far wealthier threshold than Democrats have advocated.


Boehner acknowledged that even the conservative-leaning “Plan B” did not have the support necessary to pass in the Republican-dominated House, leaving a resolution to the fiscal cliff in doubt.


“In the next few days, I’ve asked leaders of Congress to work towards a package that prevents a tax hike on middle-class Americans, protects unemployment insurance for 2 million Americans, and lays the groundwork for further work on both growth and deficit reduction,” Obama said. ”That’s an achievable goal.  That can get done in 10 days.”


Complicating matters: The halls of Congress are silent tonight. The House of Representatives began its holiday recess Thursday and Senate followed this evening.


Meanwhile, the president has his own vacation to contend with. Tonight, he was embarking for Hawaii and what is typically several weeks of Christmas vacation.


However, during the press conference the president said he would see his congressional colleagues “next week” to continue negotiations, leaving uncertain how long Obama plans to remain in the Aloha State.


The president said he hoped the time off would give leaders “some perspective.”


“Everybody can cool off; everybody can drink some eggnog, have some Christmas cookies, sing some Christmas carols, enjoy the company of loved ones,” he said. “And then I’d ask every member of Congress, while they’re back home, to think about that.  Think about the obligations we have to the people who sent us here.


“This is not simply a contest between parties in terms of who looks good and who doesn’t,” he added later. “There are real-world consequences to what we do here.”


Obama concluded by reiterating that neither side could walk away with “100 percent” of its demands, and that it negotiations couldn’t remain “a contest between parties in terms of who looks good and who doesn’t.”


Boehner’s office reacted quickly to the remarks, continuing recent Republican statements that presidential leadership was at fault for the ongoing gridlock.


“Though the president has failed to offer any solution that passes the test of balance, we remain hopeful he is finally ready to get serious about averting the fiscal cliff,” Boehner said. “The House has already acted to stop all of the looming tax hikes and replace the automatic defense cuts. It is time for the Democratic-run Senate to act, and that is what the speaker told the president tonight.”


The speaker’s office said Boehner “will return to Washington following the holiday, ready to find a solution that can pass both houses of Congress.”

Van-sized space rock is a cosmic oddball








































The shattered remains of a high-profile space rock are oddly low in organic materials, the raw ingredients for life. The discovery adds a slight wrinkle to the theory that early Earth was seeded with organics by meteorite impacts.












In April a van-sized meteor was seen streaking over northern California and Nevada in broad daylight. The fireball exploded with a sonic boom and sprayed the region with fragments. Videos, photographs and weather radar data allowed the meteor's trajectory to be reconstructed, and teams quickly mobilised to search for pieces in the foothills of the Sierra Nevada in northern California.













Researchers readily identified the meteorites as rare CM chondrites, thought to be one of the oldest types of rock in the universe. "Because the meteorites were discovered so freshly, for the first time we had a chance to study this type of meteorite in a pristine form," says Peter Jenniskens of the SETI Institute in Mountain View, California, who led the search effort and the subsequent study of the space rocks.












Jenniskens personally found a fragment in a parking lot, where it remained relatively free of soil contaminants. "That's the best you could hope for, other than landing in a freezer," says Daniel Glavin of NASA's Goddard Space Flight Center in Greenbelt, Maryland.











Battered past












CM chondrites make up only about 1 per cent of known meteorites. Most of them contain plenty of organic materials, including amino acids, the building blocks of life on Earth.













Jenniskens and colleagues found that the California fragments also have amino acids, including some not found naturally on Earth. But in three rocks collected before a heavy rainstorm, which bathed the other pieces in earthly contaminants, organics are less abundant by a factor of 1000 than in previously studied CM chondrites.












These three rocks could not have lost organics due to space "weathering": analysis of the meteorites' exposure to cosmic rays suggests the original meteor was flying through space for only about 50,000 years before hitting Earth.












Based on its trajectory and its relatively short flight time, Jenniskens thinks the meteor can be traced back to a family of asteroids dominated by 495 Eulalia, a group known as a possible source of CM chondrites. It is probably a piece that broke off during an impact, revealing the relatively pristine material inside.












So what happened to its organics? Jenniskens' team found that the meteorites are breccia – smaller rocks cemented together – which suggests that the asteroid from which they came took a series of beatings. Those impacts, or possibly other processes inside the asteroid, could have heated it enough to destroy most organic material.











Limited delivery













The result might have implications for the organics delivery theory, says Bill Bottke of the Southwest Research Institute in Boulder, Colorado.












"It shows that not all asteroids can deliver sufficient quantities. One of the disappointments is that, from a prebiotic organic chemistry perspective, it was very limited," says Bottke. "But this is an unusual case. Most [CM chondrites] are loaded with organic compounds."











Still, studying the space rocks will help us prepare future missions to asteroids such as OSIRIS-Rex, scheduled to take off for asteroid 1999 RQ36 in 2016 and bring a sample back in 2023.













"In some ways, we've had a sample, a very fresh one, come to us," says Bottke. "This is a test bed for the techniques we'll use in that mission."

Britain's Akram Khan's dance of creative destruction






PARIS: A year ago, Akram Khan was told his dance career was over. Now, with the Olympics ceremony under his belt, two films on the boil and three shows on tour, Britain's best-known choreographer could hardly be busier if he tried.

The 38-year-old ball of energy is in Paris this month with his most personal work to date, DESH, a full-length solo exploring his family roots in Bangladesh, through his signature fusion of contemporary dance with north Indian Kathak.

Khan's schedule for the coming months sounds like a plate-spinning act, but when he ripped his Achilles tendon during a rehearsal last January, doctors feared he would never dance again.

"It was very traumatic," he told AFP, "Ballet dancers don't come back after an Achilles tendon rupture. It's very rarely possible."

Shows were cancelled, plans cut short as Khan -- unable to walk for two months -- headed into a "humiliating" round of surgery and physiotherapy.

"I'm a dancer, so it's ego you know, somebody's telling you how to do a simple walk. I wanted to shoot them!"

"But from that it went into running, jogging, then jumping, then a little bit of confidence comes back.

"And then suddenly you're in the Olympics!" joked Khan, who choreographed and performed in a segment of the August opening ceremony.

In his solo DESH, a chameleonic Khan gives life to a dense cast of characters as the action shifts, dreamlike, from his south London birthplace to the grimy, noisy streets of Bangladesh over 80 visually-sumptuous minutes.

While he has recovered mobility, Khan has yet to get his full strength back, and had to make changes to perform the show, on world tour after premiering in London to rapturous reviews last year.

"You find other ways, and that was very valuable," he said, "I'm stronger in other ways."

Right now Khan is preparing a duet with the Flamenco dancer Izrael Galvan, in between touring with two more of his shows -- Gnosis and Sacred Monsters.

Come May he will premiere a creation called iTMOi inspired by Igor Stravinsky's "Rite of Spring" in the French city of Grenoble, before taking that show on the road as well.

Recent sideline projects have included teaming up with the artist Anish Kapoor to shoot a spoof "Gangnam Style" video in support of Chinese dissident artist Ai Wei Wei.

As if that wasn't enough, he is choreographing a film called "Desert Dancer", based on the true story of a young Iranian man persecuted for his love of dance, and is hoping to direct a film based on DESH.

In terms of juggling projects, Khan says he is busier than ever before. And in March he will become a father for the first time, when his Japanese dancer wife gives birth to a baby girl.

The story of Khan's injury and recovery loops back to an earlier one of how, as a little boy, he liked to break things to see what was inside.

"I was destructive as a child, I was fascinated to see things broken and put back together again," he told AFP, "I was very physical, I couldn't keep my hands still."

That was how Khan's mother started teaching her three-year-old son the folk dance Kathak, today the backbone of his art. To tire him out, like others might send a child to kick a ball around the yard.

Formal lessons followed aged seven, but it was long a battle of wills with a mother determined to share -- "impose", he jokes -- her culture with him.

"It was traumatic," said Khan, who talks with disarming candour, and wry humour, of his upbringing, "My mother used to bribe me, with toys, each performance I would get a little matchbox car."

While he jokes about his strong-willed mother, Khan is clear the "challenging relationship" in his life is with his father, bent on rooting out the Westerner in his son and making a true Bengali of him.

"DESH is very much about my father," he says of the piece, which opens with a scene showing him burying his father before pounding violently at the earth, as if to root out the story of their shared past.

Like a grown-up version of the creative destruction he displayed as a child.

Co-created with the poet Karthika Nair, the visual designer Tim Yip and the composer Jocelyn Pook, the work has a political dimension too, reflecting his sense that "everything is political" in Bangladesh, starting with the drinking water polluted by Western waste dumping.

"This is my story. It's part true, part lie," he says, "It needed to be epic, because it was very personal."

Newtown 'an assembly line of wakes and funerals'






STORY HIGHLIGHTS


  • "We have to take action," Vice President Joe Biden says

  • Nancy Lanza is buried at an undisclosed location, a family friend says

  • Adam Lanza will be buried "if anything ... in the spring," he adds

  • Three 6-year-old victims are buried; bells will ring Friday in observance of one-week mark




(CNN) -- Much of the nation was set to mark the passage of a week since last Friday, when a young Connecticut man fatally shot 27 people -- 20 of them children -- and then turned a gun on himself in a rampage that has breathed new life into the gun-control movement.


Church bells are to toll across the region at 9:30 a.m. and some websites plan to go dark in honor of the victims at the urging of Silicon Valley venture capitalist Ron Conway, who came up with the idea at a Christmas party attended by Gabby Giffords, the former Arizona congresswoman who was wounded in a 2011 shooting that killed six.


Kansas Gov. Sam Brownback and Texas Gov. Rick Perry have called for residents of their states to pause to reflect one week after the shooting rampage. Perry also asked that churches ring their bells 26 times in honor of the victims at the school.


The observances are to come a day after President Barack Obama's administration put into motion an effort to change U.S. gun laws, less than a week after the Newtown, Connecticut, school shootings.


Vice President Joe Biden met with Cabinet members and law enforcement leaders at the White House to start formulating what Obama called "real reforms right now" in the wake of the shootings that killed 27 people -- including 20 children -- and the shooter himself.


"We have to take action, and there are a number of things ... we can immediately do," Biden said moments before the meeting began. "For anything to get done, we're going to need your advocacy."


Also Thursday, burials were held for three children and two teachers killed when Adam Lanza opened fire inside Sandy Hook Elementary School.


"It's an assembly line of wakes and funerals," said Lillian Bittman, former chairwoman of the Newtown School Board. "We can't even figure out which ones to go to. There are so many."


The assembly line stretched more than 2,200 miles west to Ogden, Utah, the hometown of shooting victim Emilie Parker. The town was festooned with pink ribbons as her parents brought her body back for burial.


"This sucks -- there's no reason for us to be here tonight," her father, Robbie Parker, told friends and well-wishers at a memorial service Thursday night. "And I'm so thankful for everybody that's here."


His voice trailed off as he struggled for composure. Seeing the pink -- his slain daughter's favorite color -- made him and his wife, Alissa, "feel like we were getting a big hug from everybody."


"A lot of you don't even know who she is. A lot of you never even met her," he said. "And to see your love be expressed in that way for us was so meaningful, and we were so comforted."


Parker drew laughter when he said, "A lot of people have been asking how we're doing. My opinion is, we need to come with an alternate way to greet somebody in this country." He said the first days after the shooting felt like "we were mourning inside of a glass house, because there was so much attention on the whole situation, and it was really hard to deal with.


"But then, as we come here and we start to see and feel all your love, we just know that everybody's just deeply concerned and we can feel that love and it's from a pure place and your intentions are so pure, we don't feel like people are prying," he continued. "We understand that you guys are there with us and that your pain and your sorrow is real and it's deep."


Also buried Thursday, at an undisclosed location, was Nancy Lanza, the shooter's mother, said Donald Briggs, a friend of the family who grew up with her in Kingston, New Hampshire.


Plans had not been finalized for the burial of her son, Adam, who fatally shot her Friday at their home before targeting the Newtown school and eventually taking his own life. "That's still under discussion," Briggs said. "If anything, it would be in the spring."


Three 6-year-olds were among those buried Thursday: Allison Wyatt, who loved to draw and wanted to be an artist; Benjamin Wheeler, who loved the Beatles; and red-haired Catherine Hubbard, who loved animals.


Teachers Lauren Gabrielle Rousseau and Anne Marie Murphy were also to be buried.


Victims of the slaying


The deaths have prompted a national outpouring of sympathy that continued Thursday. Carloads of teenagers from a Minnesota school that suffered a mass shooting in 2005 headed toward Newtown to offer their support.


The bloodshed has prompted an outcry among many to address gun laws and violence.


A slight majority of Americans favor major restrictions on guns: 52%, up 5 points from a survey taken in August after the July shooting inside a movie theater in Aurora, Colorado, where 12 people died, according to a CNN/ORC International poll released Wednesday.


And 46% say they believe the government must play a role in solving the issue, up 13 points from January 2011, after the Tucson, Arizona, shooting that killed six and wounded Gabby Giffords, who was then a member of Congress.


Task force begins work


Joining Biden at Thursday's task force meeting on gun violence were Attorney General Eric Holder, Secretary of Education Arne Duncan, Homeland Security Secretary Janet Napolitano and Health and Human Services Secretary Kathleen Sebelius. Law enforcement officials also attended.


On Wednesday, Obama ordered the group to provide proposals by the end of January.


"The fact that this problem is complex can no longer be an excuse for doing nothing," he said. "The fact that we can't prevent every act of violence doesn't mean we can't steadily reduce the violence and prevent the very worst violence."


Obama highlighted suggestions to restrict gun sales to criminals and the mentally ill and to improve access to mental health care.


Holder was to travel later in the day to Connecticut to meet with law enforcement officials and first responders, a Justice Department official said.


Since the shootings, a number of conservative Democrats and some Republicans who have supported gun rights have said they are open to discussing the issue.


Sen. Dianne Feinstein, D-California, said she will introduce legislation to reinstate the assault weapons ban that expired in 2004. The White House has said that the president supports that effort.


More than 195,000 people have signed an online White House petition supporting new gun-control legislation.


The gun industry itself has been largely silent on the issue; the National Rifle Association said Tuesday it would offer "meaningful contributions to help make sure this never happens again." The group has scheduled a news conference for Friday morning.


Gun control advocates say they believe the killings have so shocked the nation's conscience that change may be possible.


"I think that we are at a historic moment," said Sen. Richard Blumenthal, D-Connecticut.


Strengthening security


In Ontario, Premier Dalton McGuinty made $10 million available to pay for security upgrades to establish a locked-door policy at 4,000 of the province's elementary schools.


"We're not going to brick up these windows; that would be unreasonable. But I believe there is a reasonable expectation by parents that when their kids go to elementary school in Ontario that we will have a locked-door policy in place," he said.


HLN journalist Rita Cosby and CNN's Matt Smith, Deborah Feyerick, Ben Brumfield, Jessica Yellin, Dave Alsup, Susan Candiotti, Sandra Endo, Faith Karimi and Daphne Sashin contributed to this report.

WASHINGTON President Barack Obama plans to observe a moment of silence at the White House on Friday morning in honor of the victims of the Connecticut elementary school massacre.

The White House says the president will observe the moment of silence at 9:30 a.m. EST, about one week after the shooting at Sandy Hook Elementary School in Newtown, Conn., in which 20 children and six adults were killed at the school.

Obama has asked Vice President Joe Biden to produce recommendations on new gun laws by next month and pledged to push new legislation without delay.

The White House said the president's observance of the shootings would take place in private without press coverage.

Fiscal Cliff 'Plan B' Is Dead: Now What?


Dec 20, 2012 11:00pm







The defeat of his Plan B — Republicans pulled it when it became clear it would be voted down — is a big defeat for Speaker of the House John Boehner.  It demonstrates definitively that there is no fiscal cliff deal that can pass the House on Republican votes alone.


Boehner could not even muster the votes to pass something that would only allow tax rates on those making more than $1 million to go up.


Boehner’s Plan B ran into opposition from conservative and tea party groups -including Heritage Action, Freedom Works and the Club for Growth – but it became impossible to pass it after Senate Democrats vowed not to take up the bill and the president threatened to veto it.  Conservative Republicans saw no reason to vote for a bill conservative activists opposed – especially if it had no hopes of going anywhere anyway.


Plan B is dead.


Now what?


House Republicans say it is now up to the Senate to act.  Senate Democrats say it is now up to Boehner to reach an agreement with President Obama.


Each side is saying the other must move.


The bottom line:  The only plausible solution is for President Obama and Speaker Boehner to do what they have failed repeatedly to do:  come up with a truly bi-partisan deal.


The prospects look grimmer than ever. It will be interesting to see if the markets react.
