I hope they do, because that is the crux of the matter. More people should be armed, it should be the polciy of every school, church, mall, home, etc. in this country.
Only then will the "Gun Free - killing zones" go away and these killers be permanently deterred when they start shooting, as opposed to after they have run out of ammo or saited their appetite in the blood of others.
