Has anyone come across any papers or books on violent street crime/ organized crime in ancient Rome. There may just be little literary evidence of it, but I can only imagine an honor based society, aggressive, and hyper-masculine with no real police force would be pretty lawless. I can only assume you had to meet violence with violence, and gather friends around you who would back you up. And it seems like the only protection you had was not to be a easy target. And as far as I can see, you had to get your own revenge for a murdered family member, or have some connections.
It also seems to me that in this environment the patronage system could sometimes end up working like modern organized crime.
Anyone have insights or resources on this topic?
