He's getting exactly what he wanted by having an article written about it and having it shared across social media. But wow, it feels so good that he got mocked in the process...
In no way do I condone his actions, so let's start with that. Coulda, shoulda, whatever, is not what his trial was about.
Given the video evidence presented, he shot in self-defense. Given Washington state's law regarding self-defense, he shot in self-defense. Not going to replay it all, you can see for yourself.
All in all, it was a clusterfuck of biblical proportions. "Should have never happened.", isn't a legal doctrine. "He went looking for trouble and found it.", isn't a thing.
As to why we're still talking about this little maggot? Fuck if I know. I'd be the first to punch him in his fat face. I would happily spend the weekend in jail and lose on a battery charge.
