This is a great thread! It, by it's very nature is something that does have in impact on ALL of us. The natural course of discussion from strictly food (production/procurement and sustainability) to the degradation of society is a normal course for this, and IS something that needs discussed.
Like Andy, I, in my normal course of providing a living for myself and my wife deal with the dregs of society routinely. Now I don't have to put up with what those in a larger metropolitan area do (at least not often), but I do still see what mankind will digress to in a somewhat normal world and that leads me to KNOW BEYOND ALL DOUBT what some will do when there is no law except what a person can provide for themselves.
