What's actually surprising is that in Colorado, 12 of the movie goers didn't return fire. Makes me wonder if movie theaters aren't weapons free zones, which in retrospect might be a crappy policy.
Again , maybe it's just me, how fast do you expect normal people to react to this even if they had guns?! Is this a Sergio Leone movie? If I had a gun and for some highly up normal paranoid reason decided it should be on me at the movies, I would still definitely be dead in a dark movie theater when some guy busts through the emergency door shooting people.
Do normal gun buyers here undergo some obligatory training of any sort? at least reflex and reaction in respect to potential shoot out situations.
To carry in public normally requires a permit, which normally requires a class and some range time to demonstrate reasonable proficiency. You don't have to be Harry Callahan, but you're expected to not be Barny Fife. Down here, it's 8 hours of class time, which I believe covers mostly the legal shoot/don't shoot aspect. It's generally assumed that a person who bothers to get a permit will be the responsible sort.
Carrying in public is a strange thing. I'm a gun owner, but I have no desire to carry it around. Plenty of others feel differently. There are a few CCW guys here, at least one of whom does prefer to have it with him at all times. He would have been armed in that theater, and I suspect would have been a good guy to have on hand. So yeah, it's somewhat surprising that nobody in the theater returned fire.
As for reflex and judgment, another interesting aspect. Very rarely is anybody particular good in a gunfight. Cops are notoriously bad shots. Somewhat surprisingly, civvies often turn out to be more adept in such a situation, because they tend to practice a lot more often. However, the important thing here is that doing nothing resulted in a very bad situation. John Q. Vigilante might pop up out of the back row and shoot the wrong guy, but the greater likelihood is that he improves the situation. Definite shitty situation loses out to possible shitty situation/possible better situation.
