Trenchcoat Mafia

The Trenchcoat Mafia was an organized crime family of liberals who were followers of Marilyn Manson. They planned an attack on Columbine High School and sent two shooters, "the Manson boys" to carry out the shootings and then scrawl "Death to Pigs" on the wall before dying as martyrs. Reportedly Marilyn Manson was angry that he had been denied a chance to cover some Beatles song.
