You aren't in danger and neither is your family, however two people are now dead because you failed to act.

WRONG!!! 2 people are dead because this shithead decided to kill! If the two people in your scenario thought like many of us, they would probably have had the means to protect themselves!
I'll respond since you are responding to what I wrote- first of all, I doubt the kid at the register is going to be carrying. And again, I'm not judging anyone here or the shooter in this story, I'm mostly reading here because it's good to imagine yourself in these situations and decide ahead of time where to draw the line. Everyone's line is different.
My line is that if I had the means to protect an innocent stranger from being murdered, I would. If it meant I went to jail, so be it. I don't think that's playing tough guy or pretending I'm batman, it's just ingrained in me.
I've jumped into altercations before (unarmed) to help a stranger, one time it cost me a broken nose, 18 stitches, a trip to the hospital, and a conversation with the police (jumped in to help an elderly man being beaten in a parking lot by 2 BGs who then turned their attention and fists to MY head) I've done stuff like that in the past on instinct. Maybe it's stupid? Maybe it will get me killed if I ever try to save a person in an armed confrontation? Who knows? I hope I never find out- but I am pretty sure where my line is drawn, and it certainly includes innocent strangers.
