People often talk about French films as if they were nothing but talky and arty, but the French have a fine tradition of policiers: tough, hardboiled cop and crime movies such as "Le Cercle Rouge" (1970) or "Un Prophete" (2009). "Mea Culpa" is one such film that packs a mighty kick: It's the type of film that will get a Tom Cruise remake three years hence that won't be half as good as the original.
