The Crips are an alliance of street gangs that is based in the coastal regions of Southern California. Founded in Los Angeles, California, in 1969, mainly by Raymond Washington and Stanley Williams, the Crips were initially a single alliance between two autonomous gangs; it is now a loosely-connected network of individual "sets", often engaged in open warfare with one another. Traditionally, since around 1973, its members have worn blue clothing. The Crips are one of the largest and most violent associations of street gangs in the United States. With an estimated 30,000 to 35,000 members in 2008, the gangs' members have been involved in murders, robberies and drug dealing, among other crimes. They have a long and bitter rivalry with the Bloods. Some self-identified Crips have been convicted of federal racketeering. Some sources suggest that the original name for the alliance, "Cribs", was narrowed down from a list of many options and chosen unanimously from three final choices, over the Black Overlords and the Assassins. Cribs was chosen to reflect the young age of the majority of the gang members. The name evolved into "Crips" when gang members began carrying around canes to display their "pimp" status. People in the neighborhood then began calling them cripples, or "Crips" for short. In February 1972 the Los Angeles Times used the term. Another source suggests "Crips" may have evolved from "Cripplers", a 1970s street gang in Watts, of which Washington was a member. The name had no political, organizational, cryptic, or acronymic meaning, though some have suggested it stands for "Common Revolution In Progress", a backronym. According to the film Bastards of the Party, directed by a member of the Bloods, the name represented "Community Revolutionary Interparty Service" or "Community Reform Interparty Service". Retired police officer Sgt. Richard Valdemar has heard allegations that "Crip" was an acronym for "Communist Revolution In Progress", though he considers this unlikely to be true.
