I feel that when it comes to elementary, middle and high school, no, guns should not be allowed. (Hear that PIONEER DISTRICT?!?!?!)
Insofar as colleges are concerened, some of those students are ingenious when it comes to weapons. Kinda reminds me of the "tools" that inmates come up with. And, with some of the violence that goes on at these campuses, maybe it's not a bad idea to have both unarmed and armed responce teams. Unarmed in the dorms and school halls but armed on patrol and in the waits.
Bottom line, I feel that it should be left to the college whether their officers are armed or not.
But that's just my opinion...
