No matter how powerful a gang, the leader ALWAYS has to answer to an old white guy in a tower. The old white guy is the Prime Mover of the entire urban gang warfare in any given city. He always has an intimidating entourage of other giant white guys who are trained to ignore emasculating insults that come from black gang leaders who report once a month.
If the old white man needs an assassination performed, his entourage will gladly take on the task and have a preconceived "catch phrase" to mutter when they kill.
Even though there are powerful street warlords, all of them are aware of where the money-making machinery is being driven - it is always in those dark, sinister towers in which the old white men reside.
Yeah, that motherfucker is some scary shit. But I insulted his goons. I'm tough.
