fact is it would deter some people from breaking in to your house, , but if you break in to my house i have to do what ever it takes to defend my family.. this could result in the burgler getting hurt or worse myself. but the thing is if i had a gun i would be able to defend myself at a distance after giving fare warning without having to get injured in hand to hand combat and who wants to get close to a man with a knife, screwdriver or crowbar etc....
i also would be all for it........
