The first place a revolution starts is with telling the 'enforcers' to go hell. When they get their asses kicked a few times the 'lords' get the message that they are next.
The revolution is as close as your phone. Bar owners need only call the police atleast once a night to report these heinous criminals. When they show up, hours later, tell them the guy is gone, they missed him. Keep calling every night and it will show on their logs. When they come to bust you for not obeying the law you have a record of your attempts to keep within the law. No citizen is required to become a law enforcement officer. If I could tackle every idiot that litters the ground with his butts and issue him a fine, then I might be so inclined.
