Gang membership represents the phenomenon of a chronic group criminal spin; accordingly, the criminality of members is greater when they belong to the gang than when they are not in the gang—either before or after being in the gang. In addition, when together, the gang criminality as a whole is greater than that of its members when they are alone. The gang operates as a whole greater than its parts and influences the behavior of its members in the direction of greater extend and stronger degree of criminality.
