Given that it's an open carry state and people walk around with weapons all the time, I say yes. And two of the criminals involved in this incident were packing.
Don't forget Kyle was in Kenosha earlier in the day painting over graffiti.
Specifically, if a couple dozen hippies and or brothers were walking around with automatic rifles or semi automatic rifles not a few douche bags with skateboards, sticks, and even a couple of hand guns, would he have still been there? I'm not so sure. To me, open carry is a bully tactic.
