He has poor judgement, and he decided to live out a fantasy of a lot of people in this country, to be a superhero and try to stop the rioting that the left is encouraging. But that is the reason: He seems to have a hard time separating fantasies from things he should actually be doing.
Of course, that is the same reason that all those rioters are there, too.
This is basically asshole on asshole violence. But, at least the 17 year old is trying to preserve social order, and at least he acted in self defense.. That is why he is a couple moral steps up from the rioters, which I guess is why Chris thinks he is being made a folk hero--people are comparing him favorably to the scum he shot. Of course, Chris hasn't provided an example of that yet. I'm not sure an offhand comment by Anne Coulter makes him a folk hero. But, he may still become a folk hero. Of course, that just means that people are living vicariously through him, wanting a society with good social order, and hoping someone will step up and take the place of the Dem authorities who refuse to live up to the responsibilities of their elected positions. He did what many are not willing to do: stand up and oppose the anarchist-marxists who are trying to destroy civil order.
If the Dems don't lock down these riots, more and more will start doing that. The outcome will not be good for us.
