I have lived in anarchistic communities were gangs were supposedly "in charge" of the security. 
Never had any problem with them. In fact I saw them helping the poor and trying to promote civilized behavior among neighbors. 
In contrast, the government mafia, the police, every time they came they created serious troubles and I saw them abusing the citizens many times. 

You guys tell a lot of tales to yourselves in your heads to keep their fragile "reality" alive.
