I live in a neighborhood of girlfriend beaters, drug addicts, alcoholics and a hell of a lot of Hells Angels bikers.
Always noise, always fights. So far, my baseball bat has been enough deterrance when they've knocked on my door asking for money or beaten up people just outside my door. I've seen enough violence for a life time.
If I could, I'd get a handgun. I have a shotgun and a 30.06, but they're stored at my parents place as I cannot fit the safe-like storage device mandatory by law into my tiny apartment.
But, IF I had a gun and they knew it, I'd probably be burglarized once every week. They'd wait til I was gone and then go hunting for it.
OTOH, there's no way they'd know whether I had it on me or not - or whether I'd return in the next two seconds holding the tool of their demise in my hands
.
I dunno. I like Denmark the way it is, but I still believe that it at least should be possible to own a handgun for self defence, if you could prove you were responsible and could pass a state regulated certification.
