Yeah, you might be right. If the teachers had been packing, they could have fought back. The guy didn't care if he died, apparently, so he may have still attacked and not as many would have died. Or, had he known that the teachers were armed, would he have, instead, chosen- like McVeigh - to use a big truck loaded with fertilizer? So, say that we arm most people and train them to be safe with guns. Do we then put our schools in 'green zones' like Baghdad? Even there, where a bomb-filled truck couldn't get in, violent people found a way to massacre. Determined people seem to find a way.

Further violence only works until the enemy adapts to it, in my opinion.
