But with the latter it would be, lets just say, more "justified". Not saying either will happen although I do think an attempt at the Insurrection Act, at least in isolated locations, will be tried. And you are right. This country is big enough that the military can't control large areas unless they start shooting. Thats where the cookie crumbles. And I do believe as "divided" as this country may seem, we are nowhere near a Civil War type division and a military starting to shoot would only pull this country more together than apart IMO. Plus they aren't being to smart about it if their reasoning is to use either to affect the midterms. They better slow their roll because in no way would this country put up with something like martial law for very long. Of course there's always the possibility of some kind of MAJOR False Flag type event, and I mean major like a dirty bomb taking out half a million people.
An ACTUAL terrorist attack like that scares me more than any other scenario actually because these guys can't even tie their shoes and we are as unprepared as perhaps anytime in our history to an attack.
