Noomi, why do you carry a spare tire in the trunk of your car?That wasn't my argument.
Then we're agreed it doesn't matter if they ever used them.
So you would want them simply because you can - not for the 0.005% chance someone might break into your home?
You hope you will never have to use it.
But it's comforting to know it's there in case you drive over a sharp object and have flat tire; especially, late at night or on a less traveled road.
A gun in the home servers the same purpose.
You pray that you will never need it..........but it's there if you do.
