There are a lot of misguided people out there. From his view point, I don't think everyone who is an American should be allowed to indiscriminantly buy,keep and bare arms without any oversight at all.I think that people who are allowed to bear arms on a regular basis in the general public should only be allowed to do so after an intense background and psychological check as well as use training the same as if they were a police officer.
I don't think that need apply to sportsmen as generally they are a set unto their own and carrying a firearm under very different circumstances and conditions than those who do so in the realm of the general public on a daily basis.
But what this guy is completly failing to notice or to address is anyone who wants to maim and murder in a public building or anywhere else is free to do so in this country.If i'm intent on murdering someone it's as simple as buying a firearm off the black market then laughing at the sign that says no firearms allowed as I walk into the building.And the ONLY thing that might stop that or to lessen the damage is if someone else in that building had a firearm as well and shot him before he shot them.
I appear in court every week as a Loss Prevention/Risk Management consultant and can tell you that the sherriff department who use metal detectors and wands is a joke. Nine times out of ten if you put on a suit and tie they wave you through without so much as a glance.And even if they do check and wand you all you have to do is simply put the gun in your pants behind your belt buckle.They wand over the buckle,contribute the hit as the buckle then tell you to keep going.
The fact is,I can enter any building in the U.S. at least as far as the entry point and start shooting the place up and there can not be a law made that could stop me from doing so.
