it depends on the gang itself. some are really loose knit and have no hierarchy while others are really organized. i know smaller black gangs(not all black but mostly) out here in ohio.. they're organized into two different branchs(i consider branches while they consider flying one flag and set). you got one side of the gang that is making money. no real leader there on that side. while on the other wing of the gang you got parties the real gang-bangers who might kill you for saying something wrong these are usually the younger ones who dont give a fuck. many street gangs aren't organized they do what they want. at the same time many are organized and can be considered organized crime groups.
