Their only purpose seems to be to inflict a lot of carnage, very quickly. What about to overthrow our tyrannical government? If that argument doesn't convince you, I suspect nothing will.I do think it's quite acceptable to arm the teachers. They are the first point of contact with any shooter and will be able to respond faster, if need be, than any law enforcement out on patrol in the streets. Wait a minute: didn't this tragedy occur as a result of a teacher not taking proper care of her weapons? Might the presence of more guns in schools just result in more shootings?
