So mine first question is very simple, have you though of the preventive measure (target hardening) first?
Yes. The hardware on our doors was upgraded, including extra-long screws holding in the strike plates, replacing the full-length glass door(!) with one with small windows, etc...
With young kids in the house the guns are all locked up. I don't want to shoot anyone (well, maybe two or three and the cat

). I'd rather they went and bothered someone else and making the house a hardened target helps with this.
That being said, it's comforting that I am allowed to defend my family rather "run away" as our only option.
