Yet, one of the men (plus the lady that grabbed the mag) that held down & stopped the shooter was a Sheepdog.
He had come out Walgreens and ran to the sound of the gunshots. He was a CCL.
No doubt there were brave souls on hand that day.
Some naturally tend to run towards the smoke while others run away and there is nothing inherently wrong with either action in the general sense.
The poster brings up some good and valid points regading the risk one faces getting involved in something like this where the bad guys may not be well identified and a good guy can be taken down or out by another good guy or by a cop.
I once had a forum discusson with a freeper who claimed that he never left the house with less than 4 hi cap mags of .45 and his pistol. He wanted to be prepared to engage shooters in public places such as malls, etc. IMO, that isn’t enough if one really expects trouble but too much for mere self defense. If one really feels the need to prepare for four reloads, maybe one should think more carefully about where one travels and try more to avoid dangerous sitations?
I think poster’s question is a very intelligent question for any person, especially those without police or military training to consider: At what point should one consider NOT inserting themselves into a gunfight?
