He would still be alive if he had been arrested for his previous attacks on law enforcement
Yes, but I find this ending, in his case, somehow more satisfying

May have something to do with him intentionally bringing a firearm along on his missions to assault ICE agents carrying out their duty.
I don’t care what anyone says. 2A is defensive in nature, right up until it is forced to flip to offensive, when fired upon by agents of the state gone bad. At that point it is called “war.”
So far, the only elements firing offensively here are these insurgents, in Utah, in Dallas, at the President, oh, and weaponizing vehicles, and I probably forgot some.
Clearly this guy, by intentionally assaulting ICE officers while armed, was looking for the opportunity/excuse to let fly.
Otherwise, why bring a gun, when literally everyone around you is on your team - except the ICE agents?

If you step back just a bit - it is pretty clear what was really going on in this thing’s head.
