Some men have a rather explicit sexual discussion. A man asks his wife to show him her breasts--she does--and we see them briefly. We see some corpses' naked bodies (no genitals)
Some very gruesome images of bloody, mangled corpses. An autopsy is performed offscreen. People are arrested fairly often and interrogated (sometimes slapped while being interrogated). A man is stabbed twice and we see blood as he falls on the floor (he dies later in the movie). Plenty of explicit discussion about murder and crime.
Around 15 f-words. An explicit sexual discussion involving sexual language. Plenty of other profanities.
There is a recurring theme of alcoholism throughout the movie. People drink to various degrees of intoxication. We see a few A.A. meetings. People smoke as well.
There is a very realistic foot-chase scene, resulting in an arrest. Most scenes described in the Violence/Gore category are fairly frightening.
