I kind of like the idea of stun guns, or sawed off shotguns so older people could shoot around corners if someone breaks into their home, not that I'm against owning higher powered guns, but wouldn't they go through walls, stun guns, and sawed off shotguns would be aimed at the intruders breaking into ones home, and wouldn't go through walls into your neighbors home, etc...
P.S. I heard in Switzerland crime is almost non existant, cause everyone owns an assault rifle. The criminal apparently is concerned about being shot at, and the elderly without guns are defenseless, and knowing an elderly might have a gun is kind of an humbling thought, if you know some of the elderly, I'd be scared to break into their home if they had a gun. The only recourse they have is to call the police, and of course the police are after the crime. The question is the legalities of shooting someone breaking into your home, but after the supreme court ruling in favor of junior being exposed to the porn on the internet, it makes one wonder if the Supreme Court is capable of interpreting the law, so in favor legalizing stun guns, to zap intruders breaking into the home, so to disable them, so you can hand cuff them, so law enforcement officers can be called, etc...
P.S. They have some quite simple wireless security systems, that if used would deter a lot of petty breakins, etc...
