Yes, in the Supreme Court case "CASTLE ROCK V. GONZALES"(See: http://en.wikipedia.org/wiki/Castle_Rock_v._Gonzales ). A woman sued the police after she asked for the police to enforce a restraining order against her ex-husband. They wouldn't enforce it, her children got killed. She sued the police and lost.

A police department can be sued for the criminal misconduct by one of its officers, if the misconduct pertains to something done during the course of their duties or otherwise related to their duties as a police officer. However, if a police officer lies to a woman at a bar in order to have a one night stand, for example, that wouldn't be grounds to sue the police department.
Anybody can file for bankruptcy.
