Dear #blackriflesmatter,
Of course I'm not saying you should rely on a burglar to allow you to retrieve a firearm. How progressive that would be!
I'm actually advocating two things. First, when not in use, lock up your firearms.
Second, I consider a firearm to be in use when it's strapped or fastened to your body, over which you have control, and carried for self-protection, protection of others, and protection of home and property.
So when the burglar comes calling (and at all other times), simply use the firearm you already have with you. Also, and more importantly, follow the 4 basic rules of firearms safety and know the laws governing the use of lethal force so you don't injure or kill someone when the use of lethal force is not warranted..
