I don't think it's really mocking Kent State, i think it's more a political statement against the government. Kent State happened a long time ago, and remember it wasn't really a school shooting, it was the National Guard that shot and killed students who were at a protest (a sit-in, think Occupy style protest), not just some crazy kid with a gun. It's not a "school shooting" in the way Columbine or Virginia Tech were.
