There are currently 72 active chapters and 4 prospective chapters across the world, with 30 of them in the United States: Alaska, California, Kentucky, Massachusetts, Minnesota, Nebraska, New York, North Carolina, South Carolina, and Ohio. Although not all members admit to being involved with the gang, it is estimated that there are between 500 and 600 individuals involved worldwide. Hell's Angels was originally formed as a military-style motorcycle club in San Francisco in 1935. Because of their association with criminal activity and the use of their logo on clothing sold by the infamous Los Angeles gang, The Hell's Angels have become widely known as a criminal organization. They also play an important role in the drug trade and have been known to kill people to protect their business interests. However, despite their reputation as criminals, the group has also been known to aid victims of crime in need and has provided security for celebrities during public appearances. The Angels also work closely with other organizations such as the Mafia to protect their businesses while maintaining their image as a violent gang. Currently, they operate completely offline and do not have any official leadership positions within the motorcycling community. However, they do have a set of rules that everyone in the club must follow called "The Bible", which includes guidelines on behavior and attire. If someone violates one of the rules, they can be expelled from the club.
