Again I think it makes more sense to keep evil and crazy folks out of schools than make restrictions on the sane and law abiding. If you could wave a magic wand and remove all the black guns from the country does any one think the attacks would stop? Crazy and evil folks would use bombs or shot guns with buck shot or things normal folks have not even thought of yet. Colombine shooters used 9mms , shotguns and bombs . The cause is the decline of our society and a lack of respect for life. It is not something that can be fixed by legislation but sadly it is the county we now live in. We need to harden our schools to protect our children.
