Hierarchy Among Gangs
Not all that you see about the biker gangs in TV shows is right, especially the part displaying messy gatherings of the gang members, that always end with fighting. In reality, the gang members have a well-organized channel of responsibilities and there exists a strict hierarchy among the members.
From the top, there are club presidents among the gangs, vice presidents, secretaries, and treasurers, coming down to the members who are on a probation period. For every role, there are specific sets of responsibilities that have to be performed with accuracy.
