On one of these (tragically all too frequent) mass shooting threads, someone posted a fascinating youtube video from one of the major American news networks (a kind of in-depth analysis piece). They took a group of college students in their early twenties and told them they were going to put them on an intensive course in handling concealed-carry weapons, with a view to making them more effective in using their weapons in self-defence. (Classic psych experiment set-up - what was actually going to be tested was quite different as will become apparent). The first day was a session on the range, lectures on situational awareness etc.
The second day started radically differently. (I presume at this stage the experiment organisers had taken the precaution of replacing the students' ammo with blanks, btw). The students were in a lecture when suddenly a masked gunman burst in and started shooting with a semi-automatic - actually staged for the experiment - the gun was shooting paint balls. None of the students, not even the young man who, prior to enrolling in the experiment had practiced down a firing range weekly, even got their guns out of their holsters before they were "killed".
Concealed carry does not make you safer - it gives an illusion of making you safer. The armed forces spend huge amounts of time training people to be combat ready - on edge, keyed up the whole time (and this can cause massive psychological difficulty on return to normal life). The rest of us, going about our daily business, are not in this hyped up state of combat readiness - we'd react as those students did, freeze, fail to get guns out of holders, etc. There is nothing you can do to protect yourself against a nutter with a gun, except create a society where the nutter cannot get hold of a semi-automatic weapon in the first place.
I have no doubt, Chilled, that you sincerely believe that you are safer with your gun. But you are kidding yourself.
