48 Hours

This newsmagazine investigates intriguing crime and justice cases that touch on all aspects of the human experience. Over its long run, the show has helped exonerate wrongly convicted people, driven the reopening -- and resolution -- of cold cases, and changed numerous lives. CBS News correspondents offer an in-depth look into each story, with the emphasis on solving the mystery at its heart. The program and its team have earned critical acclaim, including multiple Emmy, Peabody and Edward R. Murrow Awards.

Cops

Featuring police officers, constables and sheriff's deputies patrolling streets for car thieves, drug pushers, sex-trade workers, violent thugs and anyone else who dares step onto the wrong side of the law. No music, no scripted dialogue, no narration; just gritty videos of cops in action during patrols and other police activities.

Forensic Files

Eagle-eyed technical experts prove there is no such thing as a perfect crime as they assemble the pieces every criminal leaves behind. Dramatic crime re-creations and, sometimes, part of the investigations are a staple of the series. Some of the re-creations include alternate versions of the crimes, which are disproved by science. The show's episodes follow each case from the initial investigation until it reaches its legal resolution.
