Regardless of weapons, I think the poisonous part of the story is the headline.
Why include the part about being near a school except to sensationalize?
According to the story, the guy started shooting, and walked nearly half a mile. That doesn't sound like the school was the intended target to me. The sheriff spokesman even says they don't know where he was going.
Lemme see. Car breaks down enroute to school target, or the maniac stops deliberately, at least half a mile away from the school. So, to ensure the cops get him before he makes it to the school, he starts shooting moments after getting out of the car? Nope. I don't buy the school had anything to do with his plans.
Hype and sensationalism.
