Why don't you see the obvious flaws in trying to declare martial law? Even if American citizens are such puppets of the government (which is made of American citizens), and the military is such an easily wielded weapon of the government against it's people (which is comprised of those same people), why wouldn't it be easy to invoke such orders? Even if all that were true, the President is nowhere near the ultimate authority you seem to think he is. Ultimately the President has to answer to everyone, and even if he did just up and decide to declare a martial emergency, it'd take days if not weeks to put sufficient force in place to enact such rule. Meanwhile it'd take about an hour to convene a cabinet vote that would remove the President from office. Our political system has proven itself the most effective and reliable yet devised, and it's not so easy to shortcircuit that system as simply making a single decision to undermine it. Now I'm sure you'll come up with other evidence such as Singapore's oh-so-relevant mentioning here (they have never had true democracy, freedom of speech or sweeping civil rights laws) but again, whatever. I can really see how a recently appointed city-state in Asia has direct significance to American values and decision making

. I live here, I know far better than you the attitudes, emotions and willpower of the American people, and I will tell you one final time: martial law is something that would bring absolute chaos to our country. We have a higher gun to people ratio, constitutionally protected political dissent, a more highly educated populace, and great history of refusing to listen to government than any nation on this planet. But I guess that doesn't matter, I guess that in your eyes once a President has made an unjust decision and backed it with real or percieved threats, we'll all just put aside what we've worked for over the last near 250 years and decide "security" is better than freedom. Riiiight.
