13. Black Guerilla Family
Black Guerilla Family ranks 13th on our list of most dangerous gangs in America in 2018. It was founded in the 1960s at Saint Quentin State prison. Crips are strongly aligned with Black Guerilla Family which stands tall against other race-based gangs such as the Aryan Brotherhood or the Mexican Mafia. Just like most of the other gangs, the main source of income is a distribution of drugs.
