zero tolerance

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.
