...and to your point exactly, if that homicidal maniac comes to a school but all entrances are secure and the only access point is through metal detectors, and armed and trained security personnel, he will not be nearly as successful. HOPING he will change his mind because it is a GUN FREE ZONE is shear insanity and goes against plain "common sense". That same buzz word the gun grabbers like to use. Unless murderers are physically stopped, they will continue killing. Laws and signs do not physically stop anyone.
One day this truth might sink into their heads, but it will not be today, for sure.
The thing I want to know is why has it come to this? Metal detectors, security guards, whatever. What's changed since I was in school, since my kids were in school? Posting a sign that reads, gun free zone isn't what has caused this. Something within our society or perhaps the world as a whole has changed. School shootings in the past has happened. The first was in 1764, here is the list:

Notice, one in the 1700's, two in the 1800's, one in 1940 when there were no gun control laws at all. Okay, in the 1930's there was one that was passed, one had to have a federal permit to own a machine gun. Seems beginning in 1966 and especially since 1990 we have gone hog wild with school shootings. The more gun control laws, the more school shootings. That isn't a cause and effect, just something that needs pointing out. I think gun control, metal detectors, security guards are just treating the outside symptoms and not the cause. No one wants to hear that.
With every new school shooting, with the return of the fever my brain tumor patient had, we just shove more aspirin into the patient and talk more gun control while leaving the the causes, the brain tumor in place and whatever is the root cause, the motivation for these shooting in place to grow and grow. How long before these shoot graduate to something bigger and better than a gun?
