The only students/faculty with firearms will have a concealed carry permit. They have to be 21 years old. At VT as at Columbine, the police don’t do anything until after the shooting is over so what difference if they have to check on armed students/faculty?
as this event demonstrates.
The police ONLY CONTAIN they do NOT protect.
If you are therefore trapped in the containment zone, that is an acceptable situation to “protect the public”, the rest of the public. You are on your own until the police can get around to further containing the suspect. (assuming they have the right one. See this case, see the DC sniper)
That's what most people fail to see. The police don't rush in and save the innocents, it's too darned dangerous. And if you look at Katrina, it was a long time before civilization asserted itself again.
