>The only difference is, that we have "different criminals" here, so when someone gets shot, both the shooter and the shot person usually know why they're shooting and why they're being shot, and it's rarely without a good reason.

Basically the drug industry DIYing the the kind of violent enforcement of business disputes that "real businesses" use courts and state violence for. People going postal is a rounding error.
