Gun Free Zones, Malls, and the Myth of ‘Security’

I was in a mall today that had the rules posted at every entrance. If you read them, you were informed that knives, clubs, guns, and any other weapon used for personal self defense were verboten. So let me ask the readers this. If there happened to be a critical incident where an armed assailant of the terrorist variety decided that they were going to spray down the patrons with an AK-47, what would be the first line of security? There were a number of mall cops (unarmed) riding around on Segways, but they are no more than the mall version of security theater, as they would be of little use in defending anyone. Keep in mind that an AK-47 has a rate of fire up to 600 rounds per minute as demonstrated here. That means that a crazed terrorist hypothetically has the potential empty 20 mags with ease in one minute’s time, although the gun would be smokin' hot. You are probably thinking wow…that is a lot of ammo, so what could the mall cops do then? Well, since they are not armed, I would assume that they would take cover and summon the local law enforcement. They would probably arrive within four minutes, but by that time, a single shooter could have hypothetically fired 2400 rounds or 80 mags worth of ammo. Now if you multiply the number of assailants with weapons, you can see how tragic this situation could be if no one shuts the shooter(s) down before he/she/they get rolling. Okay, so the local law enforcement now arrives after a minimum of 2400 rounds have been discharged, but of course now they will need to assess the situation and formulate a plan. The SWAT teams will have also received a call out, but by this time some major carnage has already occurred, not just because a lot of people could be shot, but when the shooting begins people start to stampede like cattle and some people may be trampled and could die as well. So I ask you, what has happened to America? Americans can be vetted to a level where it is verified by their state of residence and also with a federal background check that they are competent to carry a concealed firearm, but that level of responsibility is now no longer valid once they walk through the doors of the mall. I think that it is time that people who possess concealed carry permits go on record with their discontent about this situation, and contact their local mall and ask them politely who is responsible for the safety of them and their families in the event that there ever is a critical incident such as the one detailed above. It might even be prudent to inform them on record, that if they are going to knowingly restrict you from being able to defend you and your family, that they may be putting you in a position where you might have to hold them responsible if you or your family are harmed while shopping in their mall. I am curious as to what their (lawyers) response would be. If any of the readers decide to pose this question, please be polite, and let me know the response. If I can get some time, I may go back down there and pose the question my self in person.
