For those of you who liked city of god, check out a documentary called "Bus 174". It's about a street kid who hijacks a city bus and takes hostages. It tries to show how the police and prison system are failures.
Along the same lines, there is a doc about chechen rebels who overtake a moscow theatre, it used to play on HBO. Some amazing footage, it came out around 2003.
Finally,
mostly because william s. burroughs has a part.
