The street gang control units were structured by Deputy Chief Louis Sporrer, who commanded Operations South Bureau, which was the Headquarters for the South Central Los Angeles police divisions. In 1972 street gangs were becoming a growing problem and initially were made-up of the best known gang structures of the Crips and the Bloods. A Gang Intelligence Unit was set up in 77th Street Division headed by a Sergeant Robert Michael. A uniformed team was set up and given the acronym of TRASH, or Total Resources Against Street Hoodlums, headed by Sergeant Beno Hernandez. It was from this time on that the flattering term gang was dropped and the term "hoodlums" was adopted.
