yes you said that most of the gangs in the states are on the same level...
i know that a couple of gangs like latin kings or bloods have sections in several cities but i doubt they are coordinated eachother i bet everyone can start a chapter on himself and claiming he's a blood or latin kings, its a joke
they are not an old, permanent and extremely coordinated organization like the mafia and they are involved in a couple of illegal fields at most
