Barney Miller (1974)

Barney Miller is the kind of cop we'd all like to run into. He is always sensible. He maintains order over a squad room of detectives who gamble for a hobby, get hit on by anything in skirts, go to renaissance philosophy conventions for fun, and would really prefer to be writing. Nearly all of the action takes place in the squad room where the citizens and criminals are brought in to complicate the mix.
