Definitely. Speaking of armed citizen....These days, I wouldn't help any stranger. It's not worth the headache and legal risks to me. I'd like to think, if in a setting with a mass shooter, like that Indiana kid popping the shooter, I'd do the same. Something involved a kid, sure.
But a random adult getting robbed, attacked, whatever. Nope, I'm ignoring it, maybe call the cops. But I'm not shooting someone and all that comes with it when odds are that person is an ungrateful cunt who hate people like me to begin with.
