How are you 100% sure about the bold statement?!? What if someone with a clean record just suddenly decides to snap? He can walk
anywhere freely with his weapon open and suddenly just start killing people. No one would of expected it out of him. Why? Because everyone walks around like that. That metal detecter that was normally at the door isn't there anymore because there isn't any need for it anymore since we are "protected" now
There are plenty of legal people that shouldn't carry guns, but can you tell the difference between a killer and a person in their right mind when they are both packing? You would be the 1st person begging for justice if someone close to you was hurt in a public location by a "LEGAL carrier" that shouldn't owned a gun to start with.
