ctgunfreedom beat me to it, but I'll add.......
I think last year there were some empty holster protests and some students even complained that they felt threatened by..... EMPTY HOLSTERS!!!! I recall hearing this on NRANews.com, but when I couldn't tell ya.
To answer you Alex....
I not only don't have an issue with students being armed, I think 18 should be the age for all legal adult activities. Drinking, gun permits, etc. I feel if you can take a bullet for your country and you can vote, then you should be able to practice the rest of the laws that come with adulthood.
I'll further with........
In 1974, Israel had one school shooting. Since then, there are armed teachers on campus and there has only been one incident since then.
That leads me to one conclusion....... bans on school grounds only allows the predator to know that citizens will be unarmed. you almost never hear of the guy doing a mass shooting at a gun range or similar place.
Look at what happens with the Appalachian Law School shooting..... there were two students that were armed and prevented further damage from an idiot with a firearm.
Of course, the media doesn't like to actually bring up both sides of an issue so I know most people have never even heard of the shooting:
