If I lived in America I would have to negotiate the system as it is now...which is that the bad people are armed and have no hesitation in attacking the good people using their legal or illegal guns...in home invasions, in national parks, in streets anywhere and everywhere.
They'll dress up in bandages, pretend that they can't get the couch into the back of their van without help.
They will ask you very charmingly if you can help...

["I'll push you up against the front wall, trap you, shut the doors, take you home to my place, put you in the hole, then make a dress out of you"...
