The university/college I had attended eons ago (Gallaudet University, Wash. D.C.) had an armed security force on campus. These were also officers of the Washington Police Dept. or DCPD who worked at the college on a rotation basis, some serving six to eight months and learning sign-language while performing security duties on campus with the authority granted to everyday LEO. They were there as part of the training a DCPD officer gets due to the high number of the hearing impaired population on and off campus in the city. There was an incident where a deaf person was mistaken for a (a&d) suspect and was shot because they were running (trying to catch a bus) and didn't hear the officer's call for HALT! Thus officers on the DCPD are now rotated through the university to gain awareness of the hearing impaired and better avoid the same incident. They learn rudimentary sign-language so to better communicate as the need arises (on/off campus).
Granted that this is a unqiue school, being the only liberal arts college in the country (world)for the deaf and that it is supported (in part) by Federal money (the President of the U.S. signs the graduating diplomas), thus would warrant an armed security force.
Brigham Young University in Utah, as I saw it had a security force on campus but they were not armed. Or at least the "brown-shirts" weren't. Other security officers were I believe. To my understanding the (armed) security officers were graduates of the state's police academy and likewise were granted arrest powers and work in cooperation with the city's (Provo, UT) PD.
Not all colleges/universities have this armed security force on campus with full authority of the local police dept. Would it have made a difference at VT? Probably not.
Would armed teachers and students made a difference? Again probably not. As it was stated earlier in this thread about how much more dangerous it would've been if there were hundreds of students and faculity members all shooting their weapons in panic or in an attempt to get the shooter himself? How many would've tried playing "hero"? It's a crap shoot. How many would have NOT drawn their weapons? Out of terror and shocked to immobility or inaction?
In my experience
no one person knows
exactly how they'll act in any given situation in any given moment. (yea, even me). Especially if they've never been in that given situation before. More-so if it's an extreme stress situation as in the case of a madman with a gun shooting people at random.
The military can't even give a full 100% guarantee that every-single-soldier will act as based on their training the first time they come under fire. I do believe they are getting better at it though.
Absolutely we cannot and should not berate any of the dead, wounded and uninjured for not reacting to the shooter in the manner that would've stopped him. I mean, you're sitting in class and all of the sudden someone comes in and starts shooting and one of the bullets is coming your way. Instinct for self preservation is going to take over and you're gonna hug the floor for the first few seconds. Next thing you know the shooter is gone and there are dead and wounded all around you (screaming in pain and/or terror to add to the mix here). What are you going to do? Ignore the wounded? If you got the (basic) first-aid training you should be helping them increase their chances of survival shouldn't you?
Nobody could've predicted what Cho was going to do. He was quirky and showed lots of signs of instability but he could've just as well off-ed himself in his own dorm room all by his lonesome could'nt he? Or walked off campus and never be seen or heard from again.
Though I voted yes I don't think it would've made a difference, the number of the dead/wounded would probably be smaller but the tragedy would still be there.
