[Video Link] “These are the Born Losers. The sickest sicko gang that ever terrorized a town, while the law stood helpless.” It stars Tom “Billy Jack” Laughlin.
Wikipedia has a good article about the movie:
Born Losers is a 1967 action film and the first of the Billy Jack movies. The film introduced Tom Laughlin as the half-Indian Green BeretVietnam veteran Billy Jack. Since 1954 Laughlin had been trying to produce his Billy Jack script about discrimination toward American Indians. In 1967 he decided to introduce the Billy Jack character in a quickly written script designed to capitalize on the then-popular trend in motorcycle gang movies. The story was based on a real incident from 1964 where members of the Hells Angels were arrested for raping two teenage girls in Monterey, California.
