Black bandana use is typically connected with gang membership. Law enforcement agencies associate various bandana hues and combinations with various gang affiliations.
Some of the gangs that are said to use black bandanas as a symbol of membership are Latin Kings, Black Gangster Disciples, MS 13, Vice Lords, and 18th Street.
Contrarily, Bloods typically wear red bandanas, whereas Crips are linked with the colour blue. Other methods of identifying and communicating gang affiliation include tattoos, hand signals, graffiti, and distinctive lingo. The goal of public safety initiatives to raise knowledge of typical gang insignia is to spot and stop adolescent delinquency and gang activity.
