Bad Behavior and Anarchy

I recently started getting interested in anarchy and anarchism as a social model. I have been looking at some of the videos that @dollarvigilante put out on his anarchast and have found them to be well done and informative. I have tried to bring up the topic for conversation among my friends and family, but I get looked at as if I was an alien and am either ignored or asked if I was crazy.

Anyway, the reason for this post is to try and understand one particular aspect of anarchy, and that is how it applies to bad behavior. As a newbie I apologize if I am just rehashing something which has been dealt with before. Butt seems to me that how society deals with disruptive behavior is one of the main concerns that people will have about adopting anarchy as a social model. Understandably this just arises from the strong sense of self preservation that people tend to have. Especially because of violent bad behavior, but also from behavior which is just unfair toward others.

I want to try and understand this because I have no great love for the banking system and how they are supported by government. This system causes a tremendous amount of suffering and devastation around the world and governments do not seem to do much about it. How can they, since there is so much entanglement between those in government and those in financial institutions.

A world without government control and the banking system sounds great. The one thing that stands in the way for me at the moment though, is understanding how we deal with people who are inclined to screw over others and especially be violent toward others. Without government controlling a justice system how are the disruptive people taken care of. I want to make it clear that I am not saying this as an argument against anarchism. Just that, as a newcomer who is still programmed by my upbringing, anarchy appeals to me in theory, but I need to work out this practical problem.
