Too many variables and unknowns in the scenario the OP posted. I'm not sure if he was trying to "bait" us or what.

Knee-jerk reactions to sketchy scenarios, such as this, give the anti-gunners the proverbial ammo they thrive on in order to make such comments as, "See? They're willing to pull the trigger on a shotgun only to find out that it's the paper boy making late-night collections!"...or something just as asinine.

Like I said before...not enough info to make a rational judgement.

Be smart and stay safe.
