In a year in which national attention has focused on police brutality trials in cities like Los Angeles, Detroit, and Miami, FRONTLINE crosses 'the blue line' to examine police culture and to ask what do cops think of us? Longtime police beat reporter Jack Newfield offers a close up look into the world of cops - their frustrations and their fears - through the different experiences of cops in the New York City Police Department. Key figures in New York's recent police corruption hearings are interviewed as well as Police Commissioner Raymond Kelly and members of the rank and file.
