DonT· Deplorable bitter clinger.
In general, my actions will be dictated by whether my family is with me or not. If they are with me, we're seeking cover and figuring out how to exit quickly. If I'm by myself, I'm seeking cover and trying to be a good witness, if I think it is safe for me to do so. And my default in any case is, no intervening with a firearm, unless and until I could determine good guy and bad guy definitively. If I can figure out it is a psycho randomly shooting people, I might try to engage. If it is a shootout between two thugs or two unknown armed people, not likely I would even go there.
