Remember the Appalachian Law School
In January 2002, a student opened fire on the campus of the Appalachian School of Law in Virginia, killing two administrators and a student aide. His mayhem was brought to an immediate halt when he was confronted by two students who had retrieved handguns from their vehicles.
We have seen this type of thing before in so-called “gun free zones,” where an armed citizen confronts a gunman and brings an end to a violent attack. It happened at Pearl High School in Pearl, Mississippi in 1997, when gunman Luke Woodham was confronted by assistant principal Joel Myrick, who had gotten a gun from his car and held it aimed at Woodham until police arrived.
Likewise, the New Life Center shooting in Colorado Springs in December 2007 ended abruptly when the gunman was shot and mortally wounded by a private citizen, Jeanne Assam, who was a volunteer security staffer.

The Appalachian School of Law incident shows what the Virginia Tech massacre COULD have been. Thank you for mentioning it. The national media almost universally reported tht the students "tackled and disarmed" Peter Odighizuwa, failing to mention their handguns.
A year after Seung-hui Cho's evil act, a Va. Tech student used a stolen kitchen knife to behead another student, apparently the object of an obsession. Police arrived within one minute of being called about an assault, but she was already dead.
I would, and did, risk expulsion for campus concealed carry. It IS being done, regardless. A shame preparedness is considered paranoid and a crime .
These are just a few examples of what armed law abiding citizens do every day ... just by being an armed deterrent in the face of criminals who would kill and maim an unarmed and defenseless society . Virginia Tech was a good example of the failure of gun control to protect a society. Appalachian State is a good example of an armed law abiding society and how it deterred further killing. Gun control is almost dead. Legally armed response is alive and well.

These examples alone show how everyday citizens can protect themselves and others with the ability to concealed carry a firearm. Imagine if people like the security officer and the principal did not have firearms on them, innocent lives would have been lost. I believe that is enough evidence alone to show the capabilities of what the ability to carry a concealed weapon on college campuses. Nothing can argue otherwise...it is a yes or no situation, yes carry concealed firearms and have the capability to protect yourself, or no, don't allow the carrying of concealed firearms and allow citizens to become subject to the danger that they may face.
