The answer to this problem is more freedom...not less!

Back when I was a kid people brought guns to school all the time. A lot of kids had gun racks in their pickups. We usually brought a shotgun in our vehicles during dove season so we could go dove hunting after school. Hell if you sold enough sausage and fruit in Ag class you could win a 12ga pump shotgun as the top prize. The coaches, shop teachers and ag teachers were the same way, they always had rifles or shotguns in their offices or in their vehicles during hunting season, we would even compare guns with the teachers for Christ's sake...

No one ever came and tried to shoot up our school...why, because we had the ability to return fire...
