If criminals only interact with criminals, why would what they do be illegal?
Sure they do. Rarely with any fatalities though.
Obviously it's not only between criminals, but the majority of gun violence is between them. Which is what I was talking about, if that was unclear. It's so rare that you don't have to worry about it. I mean, you could get hit by an asteroid tomorrow, but you don't worry about that, do you?
The majority of gun violence occurs between the violent criminals because that's the only situation where both sides have guns. True, the shopkeep doesn't get shot, but that's because he handed over the cash when the criminal started waving around a pistol. The mugging victim doesn't get shot, but that's because he handed over his watch and wallet as soon as the criminal pulled the gun. The home invasion robbery victims don't get shot, but that's because they cowered in a corner as soon as the criminals shoved shotguns in their faces. The rape victim doesn't get shot, but that's because she didn't resist when the rapist pointed a gun at her.
There's no violence, if you don't resist. Doesn't mean there wasn't a crime.
