Shackled inmates wearing black-and-white striped uniforms are picking up trash along Butler County highways as the sheriff there launches Ohio's first modern chain gang. Sheriff Rick Jones says he hopes the program will make the county cleaner and inmates more productive. American Correctional Association spokesman Joe Weedon says there's a national trend toward putting inmates to work, and he says escapes from such programs are rare. Jones' program involves medium-security offenders. The inmates each have one ankle shackled to the other four men on their gang. He says it teaches the inmates teamwork and keeps them from running away.
