This is someone who plays Counterstrike and reads Guns & Ammo with no other experience with guns or with gangs.
If you would have kept reading you would have seen later in the thread where he elaborated and claimed that the gang had a selection of people they could count on to send in for a straw purchase. He claimed they were more clean cut (no tattoos, colors, etc.) or females.
Not saying his claims are true, but I'm not immediately dismissing them either.
