The difference here is this isn’t someone stealing a TV, and this isn’t someone being shot / almost killed just for a prank. You have the order of operations and perspective wrong. Colie and what he intended literally doesn’t matter.
What matters is this was someone who felt threatened by a 6’5" menace who approached him, engaged him in an aggressive manner, who didn’t stop when asked, and who continued to pursue when backed away from. Result: the threatened person did what they needed to eliminate the threat. If they intended to kill they could have shot again, but didn’t. If they didn’t have a gun they would have been equally justified in beating the shit out of the attacker until they felt safe. How easy that might be for most of the “prank” victims against a 6’5" male is an open question.
Someone stealing my TV isn’t a direct threat, and so no of course I wouldn’t shot them for that. Take the TV and leave. But that’s a false narrative. It isn’t someone stealing my TV. It’s someone who has broken into my house, is in the act of committing a crime, and who I have no idea how they are going to react now that they’ve been caught. They may very well see me as a juicier target. And for that reason I would feel the need to neutralize the threat by whatever means necessary.
For the record, I do NOT own a gun, and I do believe in gun control. So let’s not bring up any gun-fetish/revenge-fantasy retorts. I’m not saying there aren’t people that have those, but right here right now they are a distraction from an honest assessment of what is going on when a person feels legitimately threatened to a “reasonable person” standard. Also, no, someone turning around in my driveway isn’t a reasonable reason to feel threatened either.
