Personally, I think that guns shouldn't be allowed on school campuses, even by school teachers. It doesn't make sense. At a school near me, this happened: http://www.sfgate.com/cgi-bin/articl...BAAT19CUPM.DTL
No guns or anything were involved; just a tackle.

If guns were allowed on college campuses by all the students, then even more fights would arise, because of the number of guns on campus; simple rivalries and such would turn violent. Just my 2 cents.
