You go in a closed room, like your bathroom. Or you install locks in all bedrooms. And you call the cops without making noises. And boom, you have no more TV but nobody's dead.

Or even better: you sell the gun and use the money to buy a lock that prevents entry without the key, plus a system that automatically pushes the door shut. With the money left over, you buy an alarm. Your home is easy to secure. And everybody would be in a far more secure place than a open thing with a gun. Your gun is far more dangerous for your family than the burglars…
