Yeah, but anti-war protests were not typically put down by the national guard. Plenty of riot gear police, but they're not shooting middle class white kids for protesting the war. Kent State was very tragic of course, but it wasn't national guard brought out to put down a riot. It was national guard protecting a building or something, and a tragic overreaction when one or more of the probably young poorly trained guardsman felt too threatened and fired when they shouldn't have .

But I think most people aren't that aware of some of the riots of the late '60s. They were a complete breakdown of order and the national guard including guns were brought out to try to restore order.

I make no judgment on the whole thing. Just a historic observation.
