First, it's supposed to be IMPOSSIBLE! for this to happen; such arms are banned from all but the government!
Second, a flat horrible multiple murder; no guns involved, so apparently(according to some) that makes it not as bad.
And unrelated to the above, but I want to post it before I lose it,
I note that the Federal government managed to put together a raid on an organic food outfit that sells only to selected customers who know precisely what they are buying, and dumped 800 gallons of raw milk that no one claimed was contaminated: but it wasn’t licensed. Your Deficit Dollars at work. We had to borrow money from the Chinese to protect you from that raw milk and all those vegetables.
