Carrying Handguns onto a College Campus?

On March 30, the House of Public Safety Committee heard and considered a bill that would allow concealed hand gun licensees to carry guns onto campus. Currently, the law is such that a gun may be brought and left in a vehicle, but cannot be carried on a person.
It has been reiterated that the bill is only pertaining to LICENSED carriers (a.k.a. LEGAL gun owners with a CHL,) and that the number of CHL carriers on a college campus is very small because to even take the first class, one must be 21 years old. These people are highly trained individuals with wonderful statistics nationwide regarding their levels of violence, accidents, etc., and are allowed to carry their concealed weapons in most buildings including but not limited to churches, state capitols, and movie theaters.
The argument against the bill is that allowing weapons on campus of any kind will only foster violence, accidents, and theft. Surprisingly (and at the same time, not surprisingly), universities and campuses are the main ones standing in opposition to this bill.
However, the argument for the bill is that by allowing legal and licensed, concealed hand guns on campus, the students will be further protected. Those for the bill promote the example of the Virginia Tech shooting: How many students would have been saved if a CHL carrier shot down the shooter faster than the shooter could shoot down innocent, unarmed citizens? Also, the North Texas Conservative blogger presents all sorts of information in this blog regarding statistics.
We can also look at this mandatory gun owndership law in Kennesaw, GA, and the statistics regarding crime rates. To sum it up, every household was required to own a gun. Crime rates? They plummeted. 3 murders since the passing of the law 16 years ago, 2 with knives and only one with a firearm.
Basically, I think allowing legal, licensed, concealed hand guns to be carried onto campus would serve only to protect in the same manner that police officers carry weapons. Only to protect, and only to be used in extreme circumstances. CHL holders are, again, highly trained individuals. Who's a raving lunatic going to attack? A campus that allows concealed, licensed weapons or one that doesn't? You decide.
