Mentally ill people don’t really understand, or follow, rules.
Everyone in a “gun free zone” is at the total mercy of the one nut who ignores the rule.
Giving that kind of power to a mentally ill person, is a totally recipe for disaster.
Most of these whacko’s, if not all, go into “gun free zones” to do their business because it is human nature, and difficult to overcome, to want to survive and get away AFTER you have slaughtered a bunch of innocent people.
“Gun Free Zone” signs should be outlawed except in courthouses.
