I should add that I get what you were saying about the use of force in that situation probably being justified & not doing it for fear of retribution. The sad fact is we share that same fear. I carry 24/7/365 & there was a time where I would have rushed to save another innocent person from an attacker but now.. probably not. If I find myself in an active shooter scenario I'm looking for the exit. If I can get my wife & myself out w/o being detected you better bet your ass that's what I'm doing. I'll call for help & give real good details from a safe distance. In the current social climate I simply can't risk what will likely happen to me financially if I do pull that trigger even if I'm cleared of any criminal wrong doing. So I get where you're coming from although I tend to give a little more leeway to Sheriff Deputies & State Patrolman who work out in the boonies by themselves when it comes to the use of lethal force. Too bad civil courts don't.
