The massive show of federal force in the Bundy case is frightening because it gives us a brief glimpse of the totalitarian regime that awaits a sleeping populace that does not take seriously its voting responsibilities and places in public office (and returns to public office) people who do not represent traditional American values.
The fact that the ranchers were well armed and willing to literally fight for their rights probably tempered the enthusiasm of the federal forces to engage in further aggression. It was clear from the body language and from some of the reported verbal responses of the government forces that they were not prepared to engage in lethal combat with fellow Americans.
Those Americans who are concerned about the possible future imposition of martial law after a financial collapse or some other event should take solace in knowing that many military and law-enforcement personnel would likely refuse to obey commands inconsistent with freedom and American values. Such commands could emanate from any political party in the future, but it is likely that such a party would be one controlling an administration that selectively enforces laws and ignores or excuses corruption.
