Dude shoots someone in the head with a rifle.Specifically killed someone who tried to brain him with a skateboard. It's not a controversial statement, the second and third shootings look like self defence. Islamic terror attacks dont happen in the middle of protests and riots, and dont end with the guy running away to hide behind a line of police cars, bizarre comparison.
End of the day, this is what violent protests, looting and arson are going to result in in modern America. It's inevitable that you'll get kids, pensioners, right wing gun lovers, KKK, normal small business owners, all arming up. Either to protect their property or just to try and start something.
People try to stop him.
He kills one.
Self defense.
I'm no legal scholar, but that doesnt seem right.
Do agree with your second part. America is fecked. Trump's just the drop that made the bucket spill over. (is that a Van Gaalism?)
