Subpar training.A number of states allow concealed carry w/o a permit.I believe what happens to some who simply obtain a handgun, strap it on and go out in public is their thoughts are filled with fanciful notions about their armed status and its responsibilities. So when something stressful takes place they have no substantive reference to manage their response and they do the wrong thing, which probably accounts for this fellow's precipitous action. I'm sure if he had been properly instructed he would have been more restrained.
A large number of states allow open carry w/o a permit.
How often does the scenario you envision actually materialize?
Further, Texas requires training to obtain a CCW -- why didn't shooter's training prevent this from happening?
