I do not want to cause offence here, I do have to ask, no Army no armed forces at all, who keeps the wolf from the door?

Try to answer this as if you are in the real world, that is Bin Laden and his ilk exist. None of this if every one put down there weapons crap either, pure simple logic is all that is asked for, how would we defend our children,family, loved one's and fellow citizens and protect our weak?
