Delinquent children are much more likely than their nondelinquent peers to die violently later in life, a study finds. And girls who ended up in juvenile detention were especially vulnerable, dying at nearly five times the rate of the general population.

"This was astonishing," says Linda Teplin, a professor of psychiatry and behavioral sciences at Northwestern University's medical school and the lead author of the study.

In Florida, one of the nation's largest school districts has overhauled its discipline policies with a single purpose in mind — to reduce the number of children going into the juvenile justice system.

It's a move away from so-called "zero tolerance" policies that require schools to refer even minor misdemeanors to the police. Critics call it a "school to prison pipeline."

Civil rights and education activists say the policy can be a model for the nation.
