Personally I'd want a battalion of Uncle Sam's Misguided Children, A10 close air support some tanks and whatever else I could get. In the absence of that because of daily life I carry a J frame. Hope if bad stuff ever comes my way I have the skill and fortitude to stop it. If a J frame isnt enough a Glock 19 w extra mags might not be enough either. Thoughts and prayers for the victims and their families.
