Cop shows. They’ve been a television staple for decades. Hill Street Blues is a classic. NYPD Blue did some new things. The Wire is a masterpiece. Sledgehammer was a hilarious oddity. And there are plenty of cheesy ones like True Justice, Criminal Minds, and the numerous cheesy permutations of of CSI. But then there was Cop Rock: the first and hopefully last police procedural musical. You read that correctly: a police procedural musical.
