I agree with you to a extent. But, statistically majority of the "First Responders"/"Pros" that will show up have about the same amount of training as your everyday carrier. I dont think its possible to simulate being shot at with live ammunition unless you've actually been shot at and know what to expect, therefore there really is no such thing as a "Pro". Sure they have a lot of time behind the trigger, but never being shot at just means you have training with shooting at paper.I agree. "If" I had ... "If" my wife ... "If" I was ... I think. Don't let that little 9 on your hip lure you into believing you should go commando and engage an active shooter. You have trained all your life to run and hide and fight only if you have too. Go with what you've trained for. All but one response on here so far has ever prepared and trained for a situation like this. Let the Pro's deal with it. Don't become part of the problem. If necessary, God forbid, prepare for "IF" it gets up close and personal.
