I'm not a fan of gun rights - but I also think he's not a murderer.... but you don't have to be a murderer to be culpable for unnecessary death and that's where he should be reflecting.

His situation isn't as binary as most would believe, but I don't think he's done the necessary self-reflection. Taking a rifle to a riot wasn't a good idea, but I don't think he understands why he wasn't the ideal person to be at the riot in the first place, why he (and young people like him) shouldn't have unsupervised access to a gun, and whether he got away with involuntary manslaughter. I'd argue it was both negligent and reckless to show up to a riot with a rifle and without military training, regardless of anything else that happened afterwards.

We're very likely to disagree on gun laws but I think we should probably both agree that children shouldn't have them - or if they do, there should be some oversight and/or restriction on how and when they use them.
