Yeah when you think about it they all fit
Service dept is the big boys calling the shots with the writing dept forming to counter them.
Crips V Bloods
The governing body sits in the their rooms calling the shots and keeping the gangs from totally killing each other while holding on to their empire. Mexican Mafia
The general bethelite population much like the real MS-13 is a group of poor boys that worship the Mexican Mafia and have no problem doing their dirty work.
The legal dept keeps it hands clean of the other gang but isn't affraid to take them on and put them in their place. It also has a way of helping out lower dubs but it still is there to make money.
And I just made up a match for the HLC but still it's a gang of it's own that worships the Mexican Mafia.
