The document summarizes the origins and characteristics of two rival Los Angeles gangs, the Crips and Bloods. The Crips formed in 1969 at Fremont High School and initially called themselves the Baby Avenues before becoming known as the Crips. The Bloods formed later to protect members from the Crips and took their name from Piru Street in Compton. Both gangs are identified by their colors - blue for the Crips and red for the Bloods. They engage in violent turf wars over territory to sell drugs. Both gangs remain active nationwide, with many members continuing the gang lifestyle they grew up with.
