An old adage I'm somewhat partial to is "A bad plan executed violently now is better than a good plan later."
Even without my carry gun, I like to think that I could have atleast attempted to intervene with my othr every day pocket items. (Swiss Army Knife, ball point pen, keys)
And who knows, once your in the arena, and are fighting with the dogs, you could claim self defense for popping one or two of them.
I was taught that as a civillian with a carry permit, my first duty is to myself and my loved ones, however, I think in that situation my duty as an Eagle Scout would override that.
