Really doesn't matter if someone is an ethnic minority or not.
Gangs and gang membership are an endless cycle of drugs, guns, violence, and death.
Most gangs require initiates to either kill a rival gang member or kill someone at random to get in. Most gangs thrive on drug and gun sales. Even the one of the oldest of gangs, the Hell's Angels (almost always Caucasian), have morphed into this deadly cycle.
I guess if someone is such a loser that gang life is the only option...maybe being the master of their own demise is a better choice...same end result, only quicker.
BTW: Something stinks about the original story. Two RIVAL gang members are boyfriend/girlfriend? Most gangs murder rivals on sight.
