I think you're right from a business perspective. The reality though is that "gang bangers" aren't killing people solely for the benefit of their drug smuggling and distribution operations. It's become a cultural thing, the change you're suggesting would require a total cultural change, which wouldn't happen anywhere near the present day. If you don't believe me, look at the slew of wealthy hip hop/rap artists who get busted with firearms or even for violent crimes. There's no reason for them to do it, but they do it anyway, because it's what they're used to.
