Gangs in prison are usually started based on the race of the prisoner. Each gang thinks they are the dominate gang in jail and will fight to stay that way. Just like street gangs, prisons gangs are usually led by a dominate figure. This person has the first and last word, and members of the gang follow their orders. They often tell the group they are there to protect them, but in reality, are only there to benefit themselves.
