If you read the comments section of that post it just shows what stupidity lurks inside people.
No concealed carry or open carry is not going to turn us into the old west with shootouts on main street at high noon. No its not going to end with everyone shooting it out over every disagreement.
My guess is that the anti constitution crowd just liked to be heard and will stop at nothing to do so.
It is too bad that the pro constitution crowd doesnt have the same voice.
