How can you be so sure that such an event would NOT occur?
You jumped to a conclusion prematurely. I never said I didn't think it wouldn't -- I said that my teachers insisted that it would happen as a direct result of legalized campus CCW. I even said as much when I said in the very next paragraph that I said trained policemen might've had a difficult time in the same situation as the students attending the seminar.
Personally, I DO think it WILL happen which is why I think campus carry is somewhat unwise. HOWEVER, my school has had one robbery at gunpoint, one rape, too many phone thefts and car thefts to count, and several arson attempts, all within the past year and a half. This makes me also believe that at this point, we should weigh the pros against the cons when dealing with CCW, and pick the lesser evil. Several of us here think that the existing CHL training requirements are already unconstitutional; to me, they seem fairly reasonable, so your results may vary.
I believe at this point it would be wise to make some kind of on-campus crisis response training mandatory for CCW applicants intending to carry on school grounds. The last thing we need is for someone to REALLY start a fight with SWAT officers and get lumped in with the actual bad guys. Apparently the school released a memorandum to the teachers regarding this subject, suggesting that all students regardless of intent, hunker down in classrooms until police arrived to take control of the situation. People caught outside of rooms during lock down, should not approach sweeping teams and instead lay down flat on their bellies without making any sudden movements; the theory behind this is the sweeping teams will move in and shoot anything that moves in a hostile manner, to secure the area for back-up units to arrive and take full measure of the scene. Whether or not this is the SAPD's doctrine toward crisis response I do not know, but it sure sounds like it would have been a good idea to formally tell this to all students instead of one teacher mention it in passing.
