If you own a gun, you can guarantee anyone less law abiding owns one to, it ups the ante and means people carry guns out of necessity or perceived necessity.
There is no reason to own a gun other than to kill people. Thats it, thats all they do. there is no practical use, there is no job made easier with a gun other than murder.
I dont fear guns, I dont live in fear of people shooting me, why? because guns are not prevalent in my society. are Americans naturallly more homicidal than europeans? I doubt it, and yet the number of murders is massively higher in the country with gun ownership....wonder why?
