The Hell's Angels is an interesting group. They are known as a motorcycle club, but they also have criminal enterprises. It is a strange dichotomy because on the one hand, you can go to a store and buy a fun Hell's Angels T-shirt. On the other hand, they deal in drugs and violence. This, of course, isn't the case for all Hell's Angels groups. Many are just about riding Harleys and organizing events. The name doesn't exactly help their image though. The Hell's Angels sounds like a criminal organization right out the gate.
What they all have in common (other than their love of motorcycles) is that they wear the same emblem, pictured here. If you see someone wearing that emblem, it is best not to mess with them. If you mess with one angel, you are messing with all of them.
