Toyota Agrees to $1B Settlement in Acceleration Case

Toyota has agreed to pay more than $1 billion to customers to settle a class action lawsuit that alleged its vehicles accelerated dangerously and without warning, according to statements by the carmaker and the plaintiffs' attorney.

The deal, which still needs approval by a federal judge in California, includes a $250 million fund to be paid to Toyota owners who sold their cars at a loss following reports of vehicle malfunctions, as well as the installation of a brake override system in about 3.25 million vehicles

An additional $250 million fund will be created to pay those owners whose vehicles are not eligible for the retrofitted brakes.

Toyota recalled more than 14 million vehicles after reports of sudden, unexplained acceleration in several models began to surface between 2009 and 2010. There were also reports of brake problems with the Prius hybrid.

Toyota insists that it was not an electrical flaw that caused the acceleration problems, but driver error, floor mats and sticky gas pedals.

Both the National Highway Traffic Safety Administration and NASA have said there is nothing in wrong with programs that run the vehicles' onboard computers

"From the very start, this was a challenging case," said Steve Berman, the plaintiffs' lawyer. "We brought in automotive experts, physicists and some of the world's leading theoreticians in electrical engineering to help us understand what happened to drivers experiencing sudden acceleration."

The settlement also includes $30 million to be given to outside groups to study automotive safety.

In a statement, Toyota agreed to the deal.

"In keeping with our core principles, we have structured this agreement in ways that work to put our customers first and demonstrate that they can count on Toyota to stand behind our vehicles." said Toyota spokesman Christopher P. Reynolds.

Mental illness, poverty haunted Afghan policewoman who killed American

KABUL (Reuters) - The Afghan policewoman suspected of killing a U.S. contractor at police headquarters in Kabul suffered from mental illness and was driven to suicidal despair by poverty, her children told Reuters on Wednesday.

The woman was identified by authorities as Narges Rezaeimomenabad, a 40-year-old grandmother and mother of three who moved here from Iran 10 years ago and married an Afghan man.

On Monday morning, she loaded a pistol in a bathroom at the police compound, hid it in her long scarf and shot an American police trainer, apparently becoming the first Afghan woman to carry out such an attack.

Narges also tried to shoot police officials after killing the American. Luckily for them, her pistol jammed. Her husband is also under investigation.

Her son Sayed, 16, and daughter Fatima, 13, described how they tried to call their parents 100 times after news broke of the shooting, then waited in vain for them to come home.

They recalled Narges's severe mood swings, and how at times she beat them and even pulled out a knife. But the children said she was consistent in bemoaning poverty.

"She was usually complaining about poverty. She was complaining to my father about our conditions. She was saying that my father was poor," Sayid said in an interview in their damp, cold two-room cement house.

On the floor beside him were his mother's prescriptions and a thick plastic bag filled with pills she tried to swallow to end the misery about a month ago. On another occasion, she cut her wrist with a razor, Sayed said.

"My father was usually calm and sometimes would say that she was guilty too because it wasn't a forced marriage. They fell in love and got married."

There was no sign in their neighborhood of the billions of dollars of Western aid that have poured into Afghanistan since the ouster of the Taliban in 2001, or of government investment.

RAW SEWAGE, STAGNANT WATER, DIRT ROADS

The lane outside their home stank of raw sewage.

Dirty, stagnant water filled holes in dirt roads nearby, where children in tattered clothes played and butchers stood by cow's hooves in shops choked by dust.

Afghanistan is one of the world's poorest nations, with a third of its 30 million residents living under the poverty line.

The sole distractions from the daily grind appeared to be a deck of playing cards and a compact disc with songs from Iranian pop singers, scattered on the floor of a room where Narges would lock herself in and weep, or sit in silence.

At times, Narges would try to focus on building her children's confidence, telling them to be guided by the Muslim holy book, the Koran, to tackle life's problems.

Sayed and Fatima said she never spoke badly of the U.S. presence in Afghanistan or of President Hamid Karzai's government.

Neighbor Mohammad Ismail Kohistani was dumbfounded to hear on the radio that Afghan officials were combing Narges' phone records to try to determine whether al Qaeda or the Taliban could have brainwashed her into carrying out a mission.

But he was acutely aware of her mental problems and often heard her scream at her husband, whose low-level job in the crime investigation unit of the police brought home little cash.

Kohistani, who operates a small sewing shop with battered machines, never imagined his neighbor could be accused of a high-profile attack that raised new questions about the direction of an unpopular war.

"I became very depressed and sad," said Kohistani, sitting on the floor few feet from a tiny wood-burning stove in Narges's home, alongside family photographs and a police training manual.

Fatima would often seek refuge in Kohistani's house when her mother's behavior became unbearable. "She did not hate us, but usually she was angry and would not talk to us," said Fatima, her eyes moist with tears.

Nevertheless, she missed her mother. The children were staying with a cousin.

"I ask the government to free my mother, otherwise our future will be destroyed," said Fatima.

Officials described it as another "insider shooting", in which Afghan forces turn on Westerners they are meant to be working with to stabilize the country. There have been over 52 such attacks so far this year.

The shooting at the police headquarters may have alarmed Afghanistan's Western allies. But some Afghans have grown numb to the violence.

Kohistani's 70-year-old father Omara Khan, who sports a white beard, sat twirling prayer beads beneath a photograph of Narges in a black veil beside one of her husband.

Asked what he thought of the attack, he laughed.

"This is common in Afghanistan," said Khan, who lived through decades of upheaval, including the 10-year Soviet occupation and a civil war that destroyed half of Kabul and killed some 50,000 civilians.

"People are killed every day."

Stevie Wonder, Gilberto Gil give Rio Christmas cheer

RIO DE JANEIRO: US singer Stevie Wonder joined Brazil's Gilberto Gil late Tuesday for a massive free Christmas concert on Rio's Copacabana beach attended by half a million people.

"Tudo bem? (Everything all right?)" Wonder shouted out to the crowd in Portuguese after being led on stage by his sons.

Dressed in a golden suit, the blind singer began his set with "What a Wonderful World", then performed hits like "I Just Called to Say I Love You", "You Are the Sunshine of My Life" and, to sing a cover of the late Michael Jackson's "The Way You Make Me Feel."

Earlier, Gil opened the show with "Realce" and "A Novidade" on a stage set with the exclusive Copacabana Palace Hotel as a backdrop.

"Good night Rio, Merry Christmas. Thank you for the gift of your presence," he said.

Up to a million spectators had been initially expected, but police estimates cited in local media put the number at 450,000 to half a million people who braved sweltering temperatures around 40 degrees Celsius on one of the hottest evenings of the year.

During a benefit concert a week ago, Wonder and Gil performed for thousands of people who paid a $400 entry fee each.

Rio is expecting to host 752,000 tourists for its lavish New Year's Eve celebrations.

Throughout the Southern hemisphere's summer season, which began on December 21 and ends in March, about 3.2 billion tourists are expected to flock to the city and spend $2.6 billion, according to Tourism Ministry figures.

For February's Carnival, the state government hopes 900,000 tourists will visit the city and spend about $665 million.

B S Yeddyurappa threatens to pull down Karnataka government

BANGALORE: A day after the ruling BJP in Karnataka sacked 30 of his followers, former chief minister and Karnataka Janata Party president B S Yeddyurappa on Tuesday threatened to destabilize the government. He said he would meet governor HR Bhardwaj with the request to ask the government to prove its majority.

"The government has been reduced to a minority. Chief minister Jagadish Shettar has no moral right to continue. I will apprise the governor of the situation," BSY told reporters in Mysore.

On Monday night, Shettar and state BJP chief KS Eshwarappa acted tough by sacking BSY followers, who were heading state-run boards and corporations, on charges of anti-party activities.

An upset BSY challenged Shettar stating that if the CM was confident of regaining power, he should dissolve the assembly and seek fresh mandate. "Let people decide who is fit enough to rule them," he said. "I will soon convene a meeting of my followers and decide the future course of action," BSY added.

BSY's plan to meet the governor is seen as a strategy to stall Shettar from presenting the budget.

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.

Gunman Killed Firemen With Bushmaster, Left Note

A convicted killer, who shot dead two firefighters with a Bushmaster assault rifle after leading them into an ambush when they responded to a house fire he set in Western New York, left behind a typewritten note saying he wanted to "do what I like doing best, killing people," police said.

William Spengler, 62, set his home and a car on fire early Monday morning with the intention of setting a trap to kill firefighters and to see "how much of the neighborhood I can burn down," according to the note he wrote and which police found at the scene. The note did not give a reason for his actions.

Spengler, who served 18 years in prison for beating his 92-year-old grandmother to death with a hammer in 1981, hid Monday morning in a small ditch beside a tree overlooking the sleepy lakeside street in Webster, N.Y., where he lived with his sister, police said today in a news conference.

Police said they found remains in the house, believed to be that of the sister, Cheryl Spengler, 67.

As firefighters arrived on the scene after a 5:30 a.m. 911 call on the morning of Christmas Eve, Spengler opened fire on them with the Bushmaster, the same semi-automatic, military-style weapon used in the Dec. 14 rampage killing of 20 children in Newtown, Conn.

"This was a clear ambush on first responders… Spengler had armed himself heavily and taken area of cover," said Gerald Pickering, the chief of the Webster Police Department.

Armed with a Smith & Wesson .38 caliber revolver, a Mossman 12-gauge shotgun, and the Bushmaster, Spengler killed two firefighters, and injured two more as well as an off-duty police officer at the scene.

As a convicted felon, Spengler could not legally own a firearm and police are investigating how he obtained the weapons.

One firefighter tried to take cover in his fire engine and was killed with a gunshot through the windshield, Pickering said.

Responding police engaged in a gunfight with Spengler, who ultimately died, likely by a self-inflicted gunshot wound to the head.

As police engaged the gunman, more houses along Lake Ontario were engulfed, ultimately razing seven of them. Some 33 people in adjoining homes were displaced by the fire.

SWAT teams were forced to evacuate residents using armored vehicles.

Police identified the two slain firefighter as Lt. Michael Chiapperini, a 20-year veteran of the Webster Police Department and "lifetime firefighter," according to Pickering, and Tomasz Kaczowka, who also worked as a 911 dispatcher.

Two other firefighters were wounded and remain the intensive care unit at Strong Memorial Hospital in Rochester, N.Y.

Joseph Hofsetter was shot once. He sustained an injury to his pelvis and has "a long road to recovery," said Dr. Nicole A. Stassen, a trauma physician.

The second firefighter, Theodore Scardino, was shot twice and received injuries to his left shoulder and left lung, as well as a knee.

Egypt approves constitution drafted by Mursi allies

CAIRO (Reuters) - Egyptian voters overwhelmingly approved a constitution drafted by President Mohamed Mursi's allies, results announced on Tuesday showed, proving that liberals, leftists and Christians have been powerless to halt the march of Islamists in power.

Final elections commission figures showed the constitution adopted with 63.8 percent of the vote in the referendum held over two days this month, giving Mursi's Islamists their third straight electoral victory since veteran autocrat Hosni Mubarak was toppled in a 2011 revolution.

Opposition groups had taken to the streets to block what they see as a move to ram through a charter that mixes politics and religion dangerously and ignores the rights of minorities.

Mursi says the text - Egypt's first constitution since Mubarak's fall - offers enough protection for minorities, and adopting it quickly is necessary to end two years of turmoil and political uncertainty that has wrecked the economy.

"I hope all national powers will now start working together now to build a new Egypt," Murad Ali, a senior official in the Muslim Brotherhood's Freedom and Justice Party, told Reuters.

"I see this as the best constitution in Egypt's history."

In a sign that weeks of unrest have taken a further toll on the economy, the government ordered new restrictions on foreign currency apparently designed to prevent capital flight. Leaving or entering with more than $10,000 cash is now banned.

Two years since waves of unrest broke out across the Middle East and North Africa - sweeping away long-entrenched rulers in Tunisia, Libya and Yemen as well as Egypt - well-organized Islamist parties have emerged as the main beneficiaries.

Urban secularists and liberals who were behind the revolts complain that their success has been hijacked.

"We need a better constitution," said Khaled Dawood, an opposition spokesman. "It does not represent all Egyptians."

Mursi's opponents say the new constitution could allow clerics to intervene in lawmaking, while offering scant protections to minorities and women. Mursi dismisses those criticisms, and many Egyptians are fed up with street protest movements that have prevented a return to normality.

Immediately after the announcement, a small group of protesters set tires on fire and blocked traffic near the central Tahrir square, the cradle of Egypt's uprising, but there were no immediate signs of violence or major demonstrations.

Washington, which provides billions of dollars a year in military and other support for Egypt and regards it as a pillar of security in the Middle East, called on Egyptian politicians to bridge divisions and on all sides to reject violence.

"President Mursi, as the democratically elected leader of Egypt, has a special responsibility to move forward in a way that recognizes the urgent need to bridge divisions," State Department spokesman Patrick Ventrell said. He noted that many Egyptians had voiced "significant concerns" over the constitutional process.

WORSENING ECONOMY

The government says its opponents are worsening the economic crisis by prolonging political upheaval. It has pledged to impose unpopular tax increases and spending cuts to win a loan package from the International Monetary Fund.

The ban on travelling with more than $10,000 in cash followed a pledge by the central bank to take unspecified measures to protect Egyptian banks. Some Egyptians have begun withdrawing their savings in fear of more restrictions.

"I am not going to put any more money in the bank and neither will many of the people I know," said Ayman Osama, father of two young children.

He said he had taken out the equivalent of about $16,000 from his account this week and planned to withdraw more, adding that he had also told his wife to buy more gold jewellery.

The "yes" vote paves the way for a parliamentary election in about two months, setting the stage for another battle between surging Islamists and their fractious opponents.

The final result, announced by the election commission, matched - to the last decimal place - an earlier unofficial tally announced by Mursi's Muslim Brotherhood.

But the opposition said it was disappointed - it had appealed for the result to be amended to reflect what it described as major vote violations during the two-round vote.

Officials said there were no violations serious enough to change the result significantly. "We have seriously investigated all the complaints," said judge Samir Abu el-Matti of the Supreme Election Committee. The final turnout was 32.9 percent.

SENSE OF CRISIS

The referendum has sharpened painful divisions in the Arab world's most populous nation and a growing atmosphere of crisis has gripped Egypt's polarized society.

Anxiety about the economy deepened this week when Standard and Poor's cut Egypt's long-term credit rating. Prime Minister Hisham Kandil told the nation of 83 million on Tuesday the government was committed to fixing the economy.

"The main goals that the government is working towards now is plugging the budget deficit, and working on increasing growth to boost employment rates, curb inflation, and increase the competitiveness of Egyptian exports," he said.

The referendum follows Islamist victories in parliamentary and presidential elections, representing a decisive shift in a country at the heart of the Arab world where Mursi's Muslim Brotherhood was suppressed for generations by military rulers.

However, secularist and liberal opposition members hope they can organize better in time for the next parliamentary vote.

Hossam El-Din Ali, a 35-year-old newspaper vendor in central Cairo, said he agreed the new constitution would help bring some political stability but like many others he feared the possible economic austerity measures lying ahead.

"People don't want higher prices. People are upset about this," he said. "There is recession, things are not moving. But I am wishing for the best, God willing."

Instagram sued over contract changes

SAN FRANCISCO: A lawsuit is seeking to stop Instagram from changing its terms of service, saying the Facebook-owned smartphone photo-sharing service is breaching its contract with users.

The class action lawsuit filed Friday by the Southern California-based Finkelstein and Krinsk law firm called on the federal court to bar Instagram from changing its rules.

"Instagram is taking its customers property rights while insulating itself from all liability," the law firm said in the filing, which also demanded that the service pay its legal fees.

"In short, Instagram declares that 'possession is nine tenths of the law and if you don't like it, you can't stop us.'"

Facebook said the complaint was "without merit." "We will fight it vigorously," the social network added.

Changes to the Instagram privacy policy and terms of service had included wording that allowed for people's pictures to be used by advertisers at Instagram or Facebook worldwide, royalty-free.

Last week, Instagram tried to calm a user rebellion by apparently backing off the changes, due to come into effect from January.

"I want to be really clear: Instagram has no intention of selling your photos, and we never did. We don't own your photos, you do," Instagram co-founder and chief Kevin Systrom said in a blog post.

But the lawsuit, filed in San Francisco, argues that Instagram didn't backpedal enough and that customers who leave the service still forfeit their rights to any photos that they had previously shared on the service.

"The purported concessions by Instagram in its press release and final version of the new terms were nothing more than a public relations campaign to address public discontent," the complaint said.

Tens of thousands of Instagram users in the state of California are eligible to join the class action lawsuit.

Govt draws up plan to revamp cyber security of critical sectors

NEW DELHI: In its bid to meet the challenge of ever increasing cyber attacks and security in the virtual world, the government has set in motion a five-year project to revamp the entire cyber security apparatus of critical sectors in the country. In the past one year, India has suffered 13,000 cyber incidents.

The responsibility for the job has been vested in National Critical Information Infrastructure Protection Centre (NCIIPC), the nodal agency to coordinate cyber security operations for critical infrastructures across the country. NCIIPC has prepared a five-year plan to completely revamp and integrate the cyber security apparatus of all critical infrastructure such as power, transportation, water, telecommunication and defence.

The agency, which is soon to be notified, further plans to set up sectoral Computer Emergency Response Teams (CERTs) that will be connected to it. It will install sensors on all critical systems to give real-time information to its command and control centre about any cyber attack to formulate quick response.

The government has also defined clear mandates for NCIIPC and CERT-IN, which is also engaged in cyber security of national infrastructure. NCIIPC will only look after absolutely critical sectors that have high threat perception coupled with greater dependence on computer and information technology (CIT), while other sectors will be with CERT-IN. These sectors (with NCIIPC) have been identified as energy (power, coal, oil and natural gas), transportation (railways and civil aviation), banking and finance, telecom, defence, space, law enforcement and security.

Functioning under the aegis of National Technical Research Organization (NTRO), NCIIPC last Monday also organized the first national conference of chief information security officers (CISO) of critical sectors of the government.

Sources said this is part of the step to first create awareness and ensure setting up of a robust security system in all critical government agencies at their own level. The task has been divided into five phases. Once agencies set up their security infrastructure, it will be connected to NCIIPC.

"There are plans to open a Cyber Security Operation Centre, a 24/7 control room for real-time information and response and a National Institute of Critical Information Infrastructure Protection for training of CISOs. We will also issue daily cyber alerts," said NCIIPC director Muktesh Chander in a presentation.

Sources said this infrastructure will ensure that NCIIPC gets real-time information as soon as a cyber attack happens on any network, can quickly analyze different attacks and provide immediate response. "If the same virus attacks different systems, we will not have to analyze them separately and formulate different responses," said an official.

National security advisor Shivshankar Menon, who addressed the gathering, stressed on participation of the private sector and said, "The NCIIPC is setting up a joint working group with representatives of industry associations to bring out guidelines for protection of critical information infrastructure in India."
