I think there was a brief taste of this during the immediate aftermath of Katrina,..
I have encountered "state of emergency" conditions after some bad hurricanes, Bertha and Fran when living in Coastal NC.
The NG was friendly, professional, and helpful, they also knew we were armed and acting as an extension of the law during a crisis.
There was NO looting, mugging people for their bags of ice or food, etc,... and we made the best of it for several days.
IF this changes, and a post Katrina martial law, is the NEW way, than we are in trouble.
"What we should have learned after 9/11 and Katrina was that those who expect government at any level to do anything more complex than garbage collection are inattentive."
Evan Marshall
"It is customary for republican governments to be bound by constitutions, and this is grand idea. The question does arise, however, about what recourse the citizen has when the government disregards its own constitution, as is the case with our own Tenth Amendment. What do you do if your government does not obey its own laws? Our Declaration declaims that when governments do not observe the God-given rights of man, it is not only the right but the duty of the people to alter or abolish them. The Declaration of Independence may not be the supreme law of the land - which is the Constitution - but it frames our philosophy of government and serves as a guide for those who respect our traditions. More people should."
