Well I think it would depend on where you live in.
There is a guy on youtube named Milk74 and he’s a white guy from the gang called the Hoovers in South central LA.
So you have people from other race that are part of a street gang of another ethnicity , simply because you from a certain neighborhood.
Then if we are talking about organized crime group… well if an organization accept people from many ethnicities, I think the only thing that would matter is if you can put in work.
Be an enforcer, money maker or something else
