It's not a "new world", it's the same world with media assisted paranoia added.
Sounds like a bunch of propaganda to me. Where are all the reports of pot farmers attacking people in Missouri ? Just another case of adjusting the laws to combat a "percieved" situation.
This last Spring a turkey hunter witnessed someone walking "suspiciously" along a dry creekbed, he reported it and had the law combing the woods for 3 days looking for a meth lab or a patch of weed. Turns out it was just an old guy looking for mushrooms. The ol'boy is lucky they didn't shoot him on site.
Just try shooting someone outside your home, while calling it self defense or whatever, and see how things work out for you from that point on. If you're afraid of meth ninja's, pot farmers, and booby traps in the woods, then stay at home or go to the mall where you feel safe. LOL
