Members of the notorious street gangs, the Bloods and the Crips, have united in cities across the country to protest the rash of police violence this nation continues to face. The rival gangs have a long history of violence between themselves, the police and the public. Coming together in protest is also a part of their history. Since their inception in the 1970s, the Bloods and Crips have united against the police when the times call for it. With the rash of police killings of black men, these times definitely call for it.
