A character gets smacked, a very humiliating form of violence. Upsetting to watch.
A good amount of the violence in this movie is rather bizarre for an R alone.
A racist cop assaults Fresh briefly by throwing his bookbag back at him in a violent manner. Not graphic at all.
We see a violent, quite traumatizing, gunfight between three rival crime families (some scenes are graphic, mostly in the beginning of the scene, but most of the fight afterwards is heard rather than scene).
A crime lord brutally beats two guys for allegedly betraying him (in the shots where we see the beating happen, it's brutal and graphic; but most of the beating is only heard, not shown onscreen).
A dog fight is seen.
