im not exactly convinced that a bunch of cowboys running around the country with guns are holding back any plans of government totalitarianism.
Yet, I'm not totally convinced the gooberment could do much of anything forcefully (IE with the use of the Military). The .gov would have to be able to totally pull the wool over the eyes of all the service men and women to be able to completely police-state us. And with as many service people I know who understand they swore to uphold the constitution and defend this country and its people, and
not the government or president or any select individual, I don't think we'd have to worry too much about that. Without the backing of our armed forces to force us to do anything you're left with a bunch of pencil pushers either too old, too overweight, or just too stupid. The American public holds a higher number of people with guns than there is government officials with guns.
Now, assuming worst case and the Pres pulls some U.N. troops, and can actually get his "civilian army" into fruition, then there might be a real chance at some horrible times to come. But the logistics of that is a timing nightmare.
