I believe it was two killed, one injured.
From what I read, he killed one guy first by shooting him the face which I don’t know if was on camera or what the situation was, and then the second guy with the skateboard by shooting him in the chest, and then shot the guy in the arm who brandished the pistol.
I also haven’t read definitively why he was “protecting” the specific business. I read he may have worked in Kenosha and was about a half hour drive from his home in the neighboring state. I’ve seen claims it was his grandfather’s business, but I don’t know if that’s accurate.
The problem that I have with this sort of vigilantism is that the legal penalty for vandalism, destruction of property, assault/battery, or looting is not death. This kid is not trained to know when the use of lethal force is appropriate, and it’s clearly inflammatory to be walking around with an assault rifle in the middle of a protest. It’s like George Zimmerman following Trayvon Martin around until Trayvon was so spooked he attacked George, and then George shoots the kid. Whether or not George was within his legal rights to shoot based on fearing for his life, he created that situation.
I do agree that attacking somebody brandishing a gun is taking your life in your hands, regardless of whether or not that attack may be justified. I could not in good conscience put myself at risk by getting in the middle of these protests, I have a 3 year old and family for which I’m responsible.
