Yes, “Polisse” is the sort of cop thriller where people do things like angrily bang on a desktop or sweep everything off it. If it happens once, it must happen six times. But every time it did, I wanted to stand up and cheer, which I‘ve never wanted to do for any such thriller.

All the cops in this movie are mad. The Paris police department here is tightening the screws on its child-protection division, and the bureaucracy has further shortened fuses that were already nubby to begin with. So if a parent is clearly guilty of neglect or molestation and receives a mere slap on the wrist, the men and women in the unit go bonkers.
