hmmm....human nature seems to be different. Only a fringe majority do more than bitch and whine in the case of martial law. The majority go into a survival mentality and try to survive what is perceived to be a transient event. Interestingly, the majority want nothing more than their creature comforts. As a result, the tyrants exploit the patriotic acts of the fringe minority to reduce the creature comforts of the minority. The majority then turn on the patriots in the hopes of assuaging the wrath of their captors.

In short, most Americas will do nothing more than some reserved grumbling.
