The most intense dread, fueled by shows like “America’s Most Wanted” and “To Catch a Predator,” is directed at the lurking stranger, the anonymous repeat offender. But most perpetrators of sexual abuse are family members, close relatives, or friends or acquaintances of the victim’s family. In 70 to 80 percent of child deaths resulting from abuse or neglect, a parent is held responsible.

Two months ago, on a wooded path in upstate New York, a psychologist named Chris Chabris strapped a video camera to a 20-year-old man and told him to chase after a jogger making his way down the path.

For close to two years Chabris, who teaches at Union College, had been conducting this same experiment. He did the experiment at night, in the afternoon, with women, with men. All were told to run after the jogger and watch him.

The goal of all this was to answer a question: Is it possible to see something really, really obvious and not perceive it?

As Mexico's wealthiest urban area, Monterrey is a symbol of the country's aspirations, with a well-educated workforce, leading universities, thousands of U.S. and other foreign business executives, and a per capita income twice the national average. But today the city is at the front of Mexican President Felipe Calderon's U.S.-backed drug war, and its future is clouded by lawlessness. As one top executive here said, "If Monterrey is lost, all is lost."

At Overthinking It, Law & Order is analyzed by two separate yet equally important groups: the people who watch the show and send in the data, and the people who build the spreadsheets. These are their findings…

Our packed prisons are starting to disgorge hundreds of mostly African-America men who, over the last few decades, we wrongly convicted of violent crimes. This is what it's like to spend nearly thirty years in prison for something you didn't do. This is what it's like to spend nearly thirty years as someone you aren't. And for Ray Towler, this is what it's like to be free.

But nearly a decade later, there’s evidence that Portugal’s great drug experiment not only didn’t blow up in its face; it may have actually worked. More addicts are in treatment. Drug use among youths has declined in recent years. Life in Casal Ventoso, Lisbon’s troubled neighborhood, has improved. And new research, published in the British Journal of Criminology, documents just how much things have changed in Portugal. Coauthors Caitlin Elizabeth Hughes and Alex Stevens report a 63 percent increase in the number of Portuguese drug users in treatment and, shortly after the reforms took hold, a 499 percent increase in the amount of drugs seized — indications, the authors argue, that police officers, freed up from focusing on small-time possession, have been able to target big-time traffickers while drug addicts, no longer in danger of going to prison, have been able to get the help they need.

To get into the parenting program, inmates must be pregnant at the time of admittance to WCCW. Any history of violence, crimes against a child, or sexual offenses will bar them from the program. The program is limited to 30 months, so women who will not be released within 30 months of their baby’s expected delivery are not eligible. Applicants sit before a screening committee to explain their crimes and why they want to be in the program. The stakes are high. Those who don’t get in must relinquish their babies to a family member or foster care within 36 hours of giving birth.

Today, Jabbar Collins works as a paralegal at the Law Offices of Joel B. Rudin in Manhattan. But for 15 years, he sat in prison, convicted of the 1994 murder of Rabbi Abraham Pollack. Mr. Collins, who maintained his innocence, spent much of those 15 years in a computerless prison law library.
