On KKTV earlier today (Colo Sprs TV station), they managed to get a reporter up to the front door very quickly, before the cops had a chance to clear all the reporters well away from the church. And she had a really short interview, that was interrupted by the cops, with a man who had been wounded in his left arm with what he was fairly certain were shotgun pellets. Of course, it could have been ricocheting plaster or concrete, right? Anyway, he was planning to go seek medical treatment eventually, to get the pieces removed, but didn't seem in a hurry to leave. He didn't consider it a very serious wound. (Unless you leave them in longterm!)
Thanks for the info on the guns.
