Sorry but you are wrong. It works about 3 million times a year in the US according to the FBI report. You might want to read it. Also, it worked for me, I stopped a mugger with my carry piece. The carrier has the real element of surprise as the criminal has no idea you are armed and if you are being mugged, it normally will not be in a crowded area. Anytime a criminal has you under a gun you are in danger of dying at his whim. If you are carrying you wait your chance, give him the money and then draw to save your life. Store owners do it everyday and they are being covered by the robber also.
Didn't draw when you should have? Your fault and does not prove concealed carry doesn't work, it proves you don't have the guts to use a weapon when you need it.
No need to be rude. The gentleman said he was old and his only mistake is forgetting there are others who have had other experiences which have worked for them.
Getting old isn't for sissies. Tie a couple of five pound weight around your wrists and then try those quick draws. Fog up your glasses and see what targets you can shoot. Run a mile and then come back and see how many targets you can hit.
I have shot with a Korean War Veteran. He did outshoot me on a man on man steel plate challenge. He's an exception to the rule.
