Behind the scenes at sheriff's office

Students shuffle in with their binders and notebooks at the start of the four-hour class every Tuesday evening, sometimes convening at an evidence collection lab or maybe the Harford County Detention Center.

In this class, there is no homework nor any pop quizzes. The only rules are to show up on time and don't wear flip-flops to class.

Thirty students - a mix of retirees, aspiring police officers, housewives and others - are taking a crash course, learning how the Harford County Sheriff's Office works.
