There were thousands of guns in schools everyday prior to the 1968 Gun Control Act.
High schools had shooting teams. So did the Boy Scouts and 4H. Kids brought firearms in, due to hunting before/after school.
(And bullying was far more common, and tolerated.)
So why weren't school shootings common?
Maybe because students were more educated on them, rather than some "boogy man" that they couldn't even pretend to carry.
Maybe because there was more discipline - both at home, and in schools.
Maybe we need to look back, and see what changed.
Your personal experience, while real and sad, is merely anecdotal and does not negate the fact that there WERE thousands of firearms in schools across the United States, every day.
Just because something is a weapon does not make it "evil".
They saying that a firearm "makes all men equal" is true.
There have been many incidents of people protected by firearms ... but they don't make the news, do they? WHY?
Could it be that doing so might possibly make people think there may be a legitimate reason to own firearms?
It is not uncommon for "kids" to gang up on someone in Portland's mass-transit train, and beat them.
The driver can't stop it. The police aren't there to stop it. If an unarmed bystander tries to stop it, they get beat up.
Only armed resistance has stopped these assaults.
Even knowing people are capable of shooting back, has stopped shooting incidents before more people were killed/injured.
So yeah ... remove all violent tendencies from humans, and then there won't need to be weapons.
Until then, I'll keep mine for self-defense ... and defense of others.
