Q: The exact number of exonerated American prisoners is unknown. But data gathered by university law schools indicates it's more than 2,000. Fascinating details surrounding some of these exonerations set them apart from the rest. Here are five recent exonerations that made headlines.

1. Michael Morton

The subject of a CNN film, Michael Morton wasn't home when his wife, Christine, was beaten to death in front of their 3-year-old son at their Austin, Texas-area home in 1986. But a prosecutor said the evidence suggested otherwise. The problem was, the jury was prevented from hearing all the evidence in the case.

Wrongly convicted of murder and sentenced to life in prison, a team of loyal supporters and DNA evidence helped Morton win his freedom in 2011. Last month, Morton's former prosecutor pleaded no contest to a court order to show cause regarding evidence that was not used in the trial.

2. Brian Banks and the incredible twist

At age 17, fearing a potentially long sentence, college football hopeful Brian Banks followed the advice of his attorney and pleaded no contest to assaulting a Long Beach, California, high school classmate in 2002.

Banks maintained his innocence throughout nearly six years of imprisonment, subsequent probation and registration as a sex offender.

But in 2011, the case took an incredible twist when the alleged victim sent Banks a Facebook friend request.

According to the California Innocence Project, the woman later admitted that Banks had not kidnapped or raped her during a consensual encounter at Long Beach Polytechnic High School, where Banks was a middle linebacker with a scholarship offer from the University of Southern California.

Q: Even kids know that we should wait for the traffic light to turn green before crossing a road, but not everybody follows this basic rule. "Chinese style road crossing" has become a hot expression recently. Chinese people "cross roads without thinking about traffic lights, so long as they are part of a crowd", said a post on Sina Weibo. A CCTV news program showed that in only an hour, more than 600 people ran red lights when crossing a road in Shijiazhuang, Hebei. Many people say that they jaywalk because the red light lasts too long. Such an opinion is supported by a research team at Tongji University. The team did research on people's waiting times at different road crossings from 2008 to 2010. They found that Chinese people would wait for 70 to 90 seconds before they lost their patience. "People are likely to run the red light when the waiting time is longer than they can bear ,"said Ni Ying, a member of the research team. However, a survey on Sina Weibo shows that nearly half of respondents believe that people jaywalk mainly because they disregard rules. "I always obey traffic rules. Time is important but safety should come first,"wrote "Qixiaoe"on Weibo. Many countries give out punishments to jaywalkers. In Singapore, the maximum can be three months in prison. Some Chinese cities have started taking some actions, too. For example, the first three people in a jaywalking group will be fined 50 yuan in Shijiazhuang. But calling on people to respect rules is more important. "To completely solve the problem, everyone should realize the importance of obeying the traffic rules,"Wang Jianping, a professor at Sichuan University, said to Huaxi Metropolis Daily.

Q: NEW DELHI, India (CNN) -- Angry workers beat to death a human resources vice president after he laid off 42 employees at an auto-parts manufacturing company in southern India, police said Wednesday.

Roy George was vice-president for human resources at Pricol, the auto-parts company.

Some four to five workers, belonging to a union not recognized by the company, barged into his office and beat him up with iron rods, said N. Kannan, a police superintendent of Coimbatore in Tamil Nadu state.

George, 47, died from his head injuries Tuesday, Kannan told CNN.

Police have arrested nine people and are expected to round up more.

Last year the Indian head of an Italian company died after allegedly being beaten by a mob of sacked employees.

More than 60 people were charged with the murder of the chief executive of Graziano Transmissioni near New Delhi.

Earlier this month, India's Jet Airways had to cancel hundreds of flights after pilots struck work over the sacking of two of their colleagues in August.

Companies in the South Asian nation, despite its rapid economic growth in recent years, have often been faced with tough labor issues because of archaic laws and company policies on hiring and retrenchment.

Business consultants in India blame such labor standoffs on what they call lack of transparency in retrenchment or layoff policies.

Hiring and firing conditions are often not explained to workers by their companies, said Rajeev Karwal, founding-director of Milagrow Business and Knowledge Solutions.

Issues could spiral out of control if the businesses and bureaucrats are seen in a "corrupt nexus" by the employees seeking reprieve from labor authorities, he said.
