When groups of veterans who had returned from overseas looking to replicate the thrills they had in World War II banded together, they quickly embraced the outlaw life - drinking, drugs, theft, and fighting. A moral panic broke out, and after the Hollister Riot of 1947 saw three gangs take over a small town for several days, a mystique was born.
Most news organizations and law enforcement officials call these bike gangs "Outlaw Motorcycle Gangs," or "OMGs." But the bikers call themselves a different name: one percenters. After the Hollister Riot, it was supposed by the American Motorcycle Association that 99% of motorcyclists were law-abiding citizens, and the last one percent were outlaws or outlaw biker gangs.
