This is the setup I keep next to my bed at night and actually carried around town (discreetly) during the
3 weeks my city was out of power after Hurricane Gustav:
Find yourself in one of the highest crime areas of your city for three weeks with absolutely no power anywhere and see if you are still worried about lawyers or prosecutors.
From a non-defensive perspective, I was lucky to have an open Chinese Buffet within walking distance so food wasn't a problem but if I was starving I could have used my Ceiner .22 kit with the AR-15/Silencer combo and quietly shot all the squirrels I could eat.
The legal arguments are as old as the silencers themselves. Bottom line is, I can't think of any better tools to defend my home with and that's all that matters to me.
