I certainly think there needs to be an increase in the availability of security personnel in these types of incidents, wether that comes from the police, local security personnel, or staff... is the debate I suppose, but I think the larger questions are how to improve over all policies and security measures to minimise deaths.
I will say that "CCW" is no more of a magic solution than those that say "ban guns", I dont see either as being a fix, and I will leave it at that, I have no desire to have a long gun control debate, im not for it (gun control), and I will leave it at that.
...In any case like I said before, its not just about what can be done to improve the odds in US states without strict gun laws...but to other places as well. My real problem is this idea of "locking down" which I think is the same as saying "if there is a fire, stay put in the building untill the fire fighters arrive", its a nutty idea, the shooting starts on another floor, and your telling the students to stay put? ughh, no. You run like hell. To the exits, right now.
