Sorry, but other armed good Samaritans, undercover officers and DEA agent aside, I'm pretty sure that if I had a CCW and was near a person shooting unarmed men, women and children, I'd take the hypothetical risk of being mistakenly shot by late arriving SWAT teams in order to try and stop the slaughter.
Yes a person with a gun shooting out with another person with a gun may be confusing enough to give one pause as to who is actually the threat, but a person with a gun shooting cowering and fleeing folks is a pretty big "stop this person" arrow in my opinion.
I don't think I'd be able to look myself in the mirror ever again if I thought that I could have stopped a massacre of innocent folks, but chose not to.
