It says a lot about the state of things there that both of them were armed when they were just out driving somewhere, and then felt that a shoot-out was the first and only correct way to settle their differences. Is driving with a gun and a piss-poor attitude mandatory or something in Florida? I am NEVER going there!
This is why I snort derisively when gun nuts crow about all that "law abiding citizen" crap. One is law abiding until one is not. In the heat of the moment, having a gun ready to hand is just asking for regrets. And I think the stats show that the erstwhile "good guy with a gun" ends up killing a family member, or himself, or gets killed by another's gun, before he takes out the "bad guy with a gun." In other words, this self defense strategy is actually more inimical to health than is staying clear of guns.
