PA-PLAYA if the would-be invaders knew that the homeowners had no means of personal protection, beyond a golf club, baseball bat, etc.?
If the invaders are coming into your house, and know you are there, they do not care what means of protection you might have.
Don't know the stats, but I'd think these types, that come in knowing you are there, will not do it in the middle of the night. They know the high % would be that you are close to any guns you might have. If they catch you watching TV in the living/family room, or eating supper/dinner....gotcha!
Don't get me wrong, guns are just fine by me(except the automatics), it's the thinking of gun owners that intrigue me.
