I am surprised that no user has commented it yet. Especially the famous IMDb DB Dumonteil. Very faithful user and very good too. I salute him. This film was one of the last real crime movie, gangster vs cops, before a long long time. Before the arrival of the great Olivier Marschall, twenty years later. The story reminds me 36, QUAI DES ORFEVRES. The story of the war between two police force flying squads. A war in which all tricks, cheats, hits ans strikes are allowed to destroy the other. You wonder who the enemy is: the gangsters of the colleagues, the fellow officers. The characters are pretty well described, you feel empathy for them. You understand their feelings. It's a dark story. Very sad and bitter as I love.
