Predicting who's at risk for violence isn't easy

CHICAGO (AP) — It happened after Columbine, Virginia Tech, Aurora, Colo., and now Sandy Hook: People figure there surely were signs of impending violence. But experts say predicting who will be the next mass shooter is virtually impossible — partly because as commonplace as these calamities seem, they are relatively rare crimes.

Still, a combination of risk factors in troubled kids or adults including drug use and easy access to guns can increase the likelihood of violence, experts say.

But warning signs "only become crystal clear in the aftermath, said James Alan Fox, a Northeastern University criminology professor who has studied and written about mass killings.

"They're yellow flags. They only become red flags once the blood is spilled," he said.

Whether 20-year-old Adam Lanza, who used his mother's guns to kill her and then 20 children and six adults at their Connecticut school, made any hints about his plans isn't publicly known.

Fox said that sometimes, in the days, weeks or months preceding their crimes, mass murderers voice threats, or hints, either verbally or in writing, things like "'don't come to school tomorrow,'" or "'they're going to be sorry for mistreating me.'" Some prepare by target practicing, and plan their clothing "as well as their arsenal." (Police said Lanza went to shooting ranges with his mother in the past but not in the last six months.)

Although words might indicate a grudge, they don't necessarily mean violence will follow. And, of course, most who threaten never act, Fox said.

Even so, experts say threats of violence from troubled teens and young adults should be taken seriously and parents should attempt to get them a mental health evaluation and treatment if needed.

"In general, the police are unlikely to be able to do anything unless and until a crime has been committed," said Dr. Paul Appelbaum, a Columbia University professor of psychiatry, medicine and law. "Calling the police to confront a troubled teen has often led to tragedy."

The American Academy of Child & Adolescent Psychiatry says violent behavior should not be dismissed as "just a phase they're going through."

In a guidelines for families, the academy lists several risk factors for violence, including:

—Previous violent or aggressive behavior

—Being a victim of physical or sexual abuse

—Guns in the home

—Use of drugs or alcohol

—Brain damage from a head injury

Those with several of these risk factors should be evaluated by a mental health expert if they also show certain behaviors, including intense anger, frequent temper outbursts, extreme irritability or impulsiveness, the academy says. They may be more likely than others to become violent, although that doesn't mean they're at risk for the kind of violence that happened in Newtown, Conn.

Lanza, the Connecticut shooter, was socially withdrawn and awkward, and has been said to have had Asperger's disorder, a mild form of autism that has no clear connection with violence.

Autism experts and advocacy groups have complained that Asperger's is being unfairly blamed for the shootings, and say people with the disorder are much more likely to be victims of bullying and violence by others.

According to a research review published this year in Annals of General Psychiatry, most people with Asperger's who commit violent crimes have serious, often undiagnosed mental problems. That includes bipolar disorder, depression and personality disorders. It's not publicly known if Lanza had any of these, which in severe cases can include delusions and other psychotic symptoms.

Young adulthood is when psychotic illnesses typically emerge, and Appelbaum said there are several signs that a troubled teen or young adult might be heading in that direction: isolating themselves from friends and peers, spending long periods alone in their rooms, plummeting grades if they're still in school and expressing disturbing thoughts or fears that others are trying to hurt them.

Appelbaum said the most agonizing calls he gets are from parents whose children are descending into severe mental illness but who deny they are sick and refuse to go for treatment.

And in the case of adults, forcing them into treatment is difficult and dependent on laws that vary by state.

All states have laws that allow some form of court-ordered treatment, typically in a hospital for people considered a danger to themselves or others. Connecticut is among a handful with no option for court-ordered treatment in a less restrictive community setting, said Kristina Ragosta, an attorney with the Treatment Advocacy Center, a national group that advocates better access to mental health treatment.

Lanza's medical records haven't been publicly disclosed and authorities haven't said if it is known what type of treatment his family may have sought for him. Lanza killed himself at the school.

Jennifer Hoff of Mission Viejo, Calif. has a 19-year-old bipolar son who has had hallucinations, delusions and violent behavior for years. When he was younger and threatened to harm himself, she'd call 911 and leave the door unlocked for paramedics, who'd take him to a hospital for inpatient mental care.

Now that he's an adult, she said he has refused medication, left home, and authorities have indicated he can't be forced into treatment unless he harms himself — or commits a violent crime and is imprisoned. Hoff thinks prison is where he's headed — he's in jail, charged in an unarmed bank robbery.

Newtown Christmas: 'We Know They'll Feel Loved'

People drawn to Newtown to share in its mourning brought cards and handmade snowflakes to town Monday while residents prepared to observe Christmas less than two weeks after a gunman killed 20 children and six educators at an elementary school.

On Christmas Eve, residents said they would light luminaries outside their homes in memory of the victims. Tiny empty Christmas stockings with the victims' names on them hung from trees in the neighborhood where the children were shot.

"We know that they'll feel loved. They'll feel that somebody actually cares," said Treyvon Smalls, a 15-year-old from a few towns away who arrived at town hall with hundreds of cards and paper snowflakes collected from around the state.

Organizers said they wanted to let the families of victims know they are not alone while also giving Connecticut children a chance to express their feelings about the shootings at Sandy Hook Elementary School.

At the Trinity Episcopal Church, less than 2 miles from the school, an overflow crowd of several hundred people attended Christmas Eve services. They were greeted by the sounds of a children's choir echoing throughout a sanctuary hall that had its walls decorated with green wreaths adorned with red bows.

The church program said flowers were donated in honor of Sandy Hook shooting victims, identified by name or as the "school angels" and "Sandy Hook families."

Season of Giving: Newtown Tragedy Inspires Country to Spread Kindness Watch Video

Gun Violence Victims, Survivors Share Thoughts After Newtown Massacre Watch Video

The service, which generally took on a celebratory tone, made only a few vague references to the shooting. Pastor Kathie Adams-Shepherd led the congregation in praying "that the joy and consolation of the wonderful counselor might enliven all who are touched by illness, danger, or grief, especially all those families affected by the shootings in Sandy Hook."

Police say the gunman killed his mother in her bed before his Dec. 14 rampage and committed suicide as he heard officers arriving. Authorities have yet to give a theory about his motive.

While the grief is still fresh, some residents are urging political activism in the wake of the tragedy. A grassroots group called Newtown United has been meeting at the library to talk about issues ranging from gun control, to increasing mental health services to the types of memorials that could be erected for the victims. Some clergy members have said they also intend to push for change.

"We seek not to be the town of tragedy," said Rabbi Shaul Praver of Congregation Adath Israel. "But, we seek to be the town where all the great changes started."

Since the shooting, messages similar to the ones delivered Monday have arrived from around the world. People have donated toys, books, money and more. A United Way fund, one of many, has collected $3 million. People have given nearly $500,000 to a memorial scholarship fund at the University of Connecticut. On Christmas Day, police from other towns have agreed to work so Newtown officers can have the time off.

In the center of Newtown's Sandy Hook section Monday, a steady stream of residents and out-of-towners snapped pictures, lit candles and dropped off children's gifts at an expansive memorial filled with stuffed animals, poems, flowers, posters and cards.

"All the families who lost those little kids, Christmas will never be the same," said Philippe Poncet, a Newtown resident originally from France. "Everybody across the world is trying to share the tragedy with our community here."

Afghan policewoman kills coalition contractor in Kabul: NATO

KABUL (Reuters) - An Afghan woman wearing a police uniform shot dead on Monday a civilian contractor working for Western forces in the police chief's compound in Kabul, NATO said.

The incident is likely to raise troubling questions about the direction of an unpopular war.

It appeared to be the first time that a woman member of Afghanistan's security forces carried out such an attack.

There were conflicting reports about the victim.

A spokesman for the NATO-led International Security Assistance Force (ISAF) said a U.S. police adviser was killed by an Afghan policewoman. Then ISAF said in a statement only that it was a "contracted civilian employee" who was killed.

Mohammad Zahir, head of the police criminal investigation department, described the incident as an "insider attack" in which Afghan forces turn their weapons on Western troops they are supposed to be working with. He initially said the victim was a U.S. soldier.

After more than 10 years of war, militants are capable of striking Western targets in the heart of the capital, and foreign forces worry that Afghan police and military forces they are supposed to work with can suddenly turn on them.

The policewoman approached her victim as he was walking in the heavily guarded police chief's compound in a bustling area of Kabul. She then drew a pistol and shot him once, a senior police official told Reuters.

The police complex is close to the Interior Ministry where in February, two American officers were shot dead at close range at a time anger gripped the country over the burning of copies of the Muslim holy book at a NATO base.

"She is now under interrogation. She is crying and saying 'what have I done'," said the official, of the police officer who worked in a section of the Interior Ministry responsible for gender awareness issues.

TIPS FOR TROOPS

The insider incidents, also known as green-on-blue attacks, have undermined trust between coalition and Afghan forces who are under mounting pressure to contain the Taliban insurgency before most NATO combat troops withdraw by the end of 2014.

Security responsibilities in a country plagued by conflict for decades will be handed to Afghan security forces.

Many Afghans fear a civil war like one dominated by warlords after the withdrawal of Soviet occupying forces in 1989 could erupt again, or the Taliban will make another push to seize power if they reject a nascent peace process.

At least 52 members of the NATO-led International Security Assistance Force have been killed this year by Afghans wearing police or army uniforms.

Insider attacks now account for one in every five combat deaths suffered by NATO-led forces in Afghanistan, and 16 percent of all U.S. combat casualties, according to 2012 data.

Hoping to stop the increase in the attacks, Afghan Defense Ministry officials have given their troops tips in foreign culture.

They are told not to be offended by a hearty pat on the back or an American soldier asking after your wife's health.

NATO attributes only about a quarter of the attacks to the Taliban, saying the rest are caused by personal grievances and misunderstandings. Last year, there were 35 deaths in such attacks.

Afghan forces are vulnerable to "insider attacks" of their own. In Jawzjan province in the north, a police commander shot and killed five comrades overnight, the Interior Ministry said.

Last year, he defected from the Taliban, said the ministry.

Taliban spokesman Zabihullah Mujahid said in a statement that the commander had rejoined the Taliban. That could not be confirmed.

Antarctic ice sheet warming faster than thought: study

PARIS: The West Antarctic Ice Sheet, whose melt may be responsible for 10 percent of the sea-level rise caused by climate change, is warming twice as quickly as previously thought, a study said Sunday.

A re-analysis of temperature records from 1958 to 2010 revealed an increase of 2.4 degrees Celsius (36.3 degrees Fahrenheit) over the period -- three times the average global rise.

The increase was nearly double what previous research had suggested, and meant this was one of the fastest-warming regions on Earth, according to paper co-author David Bromwich of the Byrd Polar Research Center.

"Our record suggests that continued summer warming in West Antarctica could upset the surface balance of the ice sheet, so that the region could make an even bigger contribution to sea-level rise than it already does," he said.

Scientists believe the shrinking of the West Antarctic Ice Sheet is responsible for about 10 percent of global warming-related sea-level rise, which if unchecked threatens to flood many coastal cities within a few generations.

The sheet, a huge mass of ice up to four kilometres (2.5 miles) thick that covers the land surface and stretches into the sea, is melting faster than any other part of Antarctica.

Data records kept at Byrd Station in the central West Antarctic had been incomplete.

Since being established in 1957, the research station has not been consistently occupied and has seen frequent power outages, especially during the long polar night, when its solar panels cannot recharge.

Bromwich and a team from several US-based research institutions used weather data from different sources to plug holes in the Byrd data and corrected calibration errors.

The updated log was published in the journal Nature Geoscience.

"Aside from offering a more complete picture of warming in West Antarctica, the study suggests that if this warming trend continues, melting will become more extensive in the region in the future," said Bromwich.

The UN Intergovernmental Panel on Climate Change in 2007 had projected sea level rise of 18 to 59 centimetres (seven to 23 inches) worldwide by the year 2100.

But a study by the US National Research Council said in June the actual rise could be two to three times higher, with polar ice-cap melt speeding up the process.

Putin targets arms deals, doubling trade on India visit today

NEW DELHI: Russian President Vladimir Putin pledged to tighten defence ties with India and double levels of bilateral trade within three years as he headed to New Delhi for a summit on Monday.

Accompanied by several senior ministers and military officials, Putin will meet Prime Minister Manmohan Singh on a one-day visit designed to highlight the strong ties between two traditional allies and fellow BRICS.

"I would like to stress that deepening of friendship and cooperation with India is among the top priorities of our foreign policy," Putin wrote in an article for The Hindu, an Indian daily, ahead of his visit.

India is now the world's largest arms importer and Russian-made military equipment accounts for 70 per cent of Indian arms supplies.

However, while Russia once had a virtual monopoly over India's arms market, New Delhi has been shopping around of late and the visit is seen in Moscow as a chance to regain lost ground and develop joint projects.

"The strategic nature of partnership between India and Russia is witnessed by the unprecedented level of our military and technical cooperation," Putin wrote in his article, saying "the joint development of advanced armaments rather than just purchasing military products" would be key to future relations.

His comments echoed those of Indian Foreign Minister Salman Khurshid who said Friday that "India is committed to strengthening and enhancing this relationship, both on economic and strategic ties".

"There is a lot of work in progress and a lot of issues and agreements will be taken up," he told reporters.

The Kremlin has said that a number of major contracts on military-technical cooperation would be inked during the visit — Putin's first to South Asia since his return to the Kremlin in May.

Likely tie-ups are expected to involve Russia's Sukhoi aircraft manufacturer, including a $3.77 billion deal for 42 Su-30MKI fighters and a deal to produce the fifth generation Sukhoi fighter — a joint Russia-India project, according to Igor Korotchenko, director of the Centre for Analysis of World Arms Trade.

Moscow has been worried recently by New Delhi's increasing preference for western suppliers, especially after Boeing was chosen last month over Russia's MiL plant for a major helicopter contract.

India has also been unhappy with delays of deliveries of some naval equipment, notably of the aircraft carrier Admiral Gorshkov, which is being refurbished for the Indian Navy at Russia's Sevmash naval yard.

Russia was originally to deliver the upgraded vessel in August 2008, but the date has now been pushed back to the end of 2013, while the price has more than doubled to $2.3 billion.

According to Indian government figures, bilateral trade has been growing steadily and is expected to reach around 10 billion dollars in 2012, up from 7.5 billion in 2009.

Putin set out a goal of doubling bilateral trade in just three years.

"Our trade turnover has overcome the consequences of global crisis, and in 2012 we expect to reach record numbers, over $10 billion. Our next goal is to reach $20 bln already by 2015," he said.

Russia and India are both so-called BRICS, the bloc of emerging powers which is seeking to act as a counterweight to western powers and which also includes Brazil, China and South Africa.

India is hoping Russia will help it achieve its ambition of joining an expanded UN Security Council which currently only has five permanent members — Russia, China, the United States, France and Britain.

The Kremlin said that Russia sees India "as one of the worthy and strong candidates for a permanent seat in the expanded UN Security Council".

As well as his talks with Singh, Putin is also due to meet the ruling Congress party chief Sonia Gandhi and Sushma Swaraj, leader of the opposition BJP.

Egyptians back new constitution in referendum

CAIRO (Reuters) - An Islamist-backed Egyptian constitution won approval in a referendum, rival camps said on Sunday, after a vote the opposition said would sow deep social divisions in the Arab world's most populous nation.

The Islamist Muslim Brotherhood, which propelled President Mohamed Mursi to power in a June election, said an unofficial tally showed 64 percent of voters backed the charter after two rounds of voting that ended with a final ballot on Saturday.

An opposition official also told Reuters their unofficial count showed the result was a "yes" vote, while party spokesmen said there had been a series of abuses during the voting.

The main opposition coalition, the National Salvation Front, responded to the defeat by saying it was moving towards forming a single political party to challenge the Islamists who have dominated the ballot box since strongman Hosni Mubarak was overthrown two years ago.

Members of the opposition, taking heart from a low turnout of about 30 percent of voters, pledged to keep up pressure on Mursi through peaceful protests and other democratic means.

"The referendum is not the end of the road," said Khaled Dawoud, a spokesman for the National Salvation Front. "It is only the beginning of a long struggle for Egypt's future."

The referendum committee may not declare official results for the two rounds until Monday, after hearing appeals. If the outcome is confirmed, a parliamentary election will follow in about two months.

Mursi's Islamist backers say the constitution is vital for the transition to democracy, nearly two years after Mubarak was ousted in a popular uprising. It will provide the stability needed to help a fragile economy, they say.

The constitution was "a historic opportunity to unite all national powers on the basis of mutual respect and honest dialogue for the sake of stabilizing the nation," the Brotherhood said in a statement.

RECIPE FOR UNREST

The opposition accuses Mursi of pushing through a text that favors Islamists and ignores the rights of Christians, who make up about 10 percent of the population, as well as women. They say it is a recipe for further unrest.

The opposition said voting in both rounds was marred by abuses. However, an official said the overall vote favored the charter.

"The majority is not big and the minority is not small," liberal politician Amr Hamzawy said, adding that the National Salvation Front would use "all peaceful, democratic means" such as protests to challenge the constitution.

The vote was split over two days as many judges had refused to supervise the ballot, making a single day of voting impossible.

During the build-up to the vote there were deadly protests, sparked by Mursi's decision to award himself extra powers in a November 22 decree and then to fast-track the constitutional vote.

The new basic law sets a limit of two four-year presidential terms. It says the principles of sharia, Islamic law, remain the main source of legislation but adds an article to explain this. It also says Islamic authorities will be consulted on sharia - a source of concern to Christians and others.

ABUSES

Rights groups reported what they said were illegalities in voting procedures. They said some polling stations opened late, that Islamists illegally campaigned at some polling places, and complained of irregularities in voter registration.

But the committee overseeing the two-stage vote said its investigations showed no major irregularities in voting on December 15, which covered about half of Egypt's 51 million voters. About 25 million were eligible to vote in the second round.

The Brotherhood said turnout was about a third of voters.

The opposition says the constitution will stir up more trouble on the streets since it has not received sufficiently broad backing for a document that should be agreed by consensus, and raised questions about the fairness of the vote.

In the first round, the district covering most of Cairo voted "no," which opponents said showed the depth of division.

"I see more unrest," said Ahmed Said, head of the liberal Free Egyptians Party and a member of the opposition Front.

He cited "serious violations" on the first day of voting, and said anger against Mursi was growing. "People are not going to accept the way they are dealing with the situation."

At least eight people were killed in protests outside the presidential palace in Cairo this month. Islamists and rivals clashed in Alexandria, the second-biggest city, on the eves of both voting days.

Sydney Harbour floating heliport plan on hold

SYDNEY: A plan for wealthy executives and tourists landing in Sydney to flit directly to the city's famous harbour via a floating heliport has been put on hold after fierce public opposition.

The company that was set up to run the operation, providing for quick transfers to and from Sydney airport and scenic flights over the harbour, said it wanted to further consider the operation's "feasibility".

"It is Newcastle Helicopter's intention to address the relevant concerns and queries with thoroughly considered and accurate information, and is taking the appropriate steps to do so," it said in a statement late Saturday.

It followed rising public anger over the New South Wales state government giving the go-head last month to unlimited flights from a barge anchored on the harbour, which is popular for yachting and close to residential areas.

According to reports, the Roads and Maritime Services (RMS) issued the licence without consulting the community, doing an environmental impact assessment, testing for noise, or putting the project out to tender.

The Sydney Morning Herald also claimed approval was given two weeks before authorities asked about air safety or air traffic control regulations.

New South Wales Deputy Premier Andrew Stoner last week insisted all usual procedures had been followed.

"As required by RMS, the proponent wrote to relevant councils in October outlining the proposal and inviting feedback but received no responses," he said in a statement.

Federal MP Malcolm Turnbull led the campaign against the heliport and said the decision had descended into farce.

"If you put this into an episode of 'Yes, Minister', nobody would believe it," he told reporters, referring to the satirical British comedy show, which revolves around the inner workings of government.

Industry leaders have long called for a heliport based in the city, which last had one in the late 1980s operating from the Darling Harbour tourist precinct.

Two more toy trains running on Kalka-Shimla route to meet tourist rush

CHANDIGARH: Tourists who are looking forward to celebrating Christmas and New Year in Shimla have a better option to reach the hill station with two more toy trains running on the Kalka-Shimla route from Friday. Seeing the rush from West Bengal and Delhi in particular, Northern Railways started the two toy trains from Kalka to Shimla. The departure timings of these trains from Kalka have been fixed in such a manner that it gets connected with other trains' arrival at Kalka.

The first toy train with a capacity of about 100 passengers leaves at 6.30am. All coaches are first class. The timings of this train are such that those arriving on board Howrah-Kalka mail at 4.30am can board it. The second toy train departs at 12.45pm and is connected with the Himalayan Queen and Shatabdi from Delhi arriving at Kalka at 11.20 am and 11.40am, respectively. This toy train has first and second class bogies with a total capacity of about 150 people.

"We have started two toy trains and timings have been fixed in such a manner that it gets connected with the other trains arriving at Kalka. These two trains will continue its services till the first week of January, but seeing the rush it can be extended also," said P K Sanghi, DRM, Ambala division.

Apart from these two toy trains, Northern Railways is already running five toy trains from Kalka to Shimla.

The 97-km track, figuring in UNESCO world heritage list, has over 900 sharp curves besides 102 tunnels and 988 bridges. It is the sharp curves which have made the proposal of increasing speed of the trains not feasible as it could result in accidents on the curves, sources said.

Lanza's medical records haven't been publicly disclosed and authorities haven't said if it is known what type of treatment his family may have sought for him. Lanza killed himself at the school.

Jennifer Hoff of Mission Viejo, Calif. has a 19-year-old bipolar son who has had hallucinations, delusions and violent behavior for years. When he was younger and threatened to harm himself, she'd call 911 and leave the door unlocked for paramedics, who'd take him to a hospital for inpatient mental care.

Now that he's an adult, she said he has refused medication, left home, and authorities have indicated he can't be forced into treatment unless he harms himself — or commits a violent crime and is imprisoned. Hoff thinks prison is where he's headed — he's in jail, charged in an unarmed bank robbery.
