It's called continuity of government. At one time it meant protecting critical government infrastructure. Now it means that it is more important to protect political control than to actually do anything to help the public. The Ferguson riots the other night provide a perfect example. Roger L. Simon notes:
Not quite cancer but pretty bad is Jay Nixon, the governor of Missouri. Not only did he attempt to prejudge the case, calling for Wilson’s head like some minor league Robespierre months before there was any evidence, but then, on the night of the grand jury announcement, after having brought in the National Guard, he goes completely AWOL and doesn’t use the Guards at all, leaving the poor store owners of Ferguson to fend for themselves, not to mention the police. Everyone got to watch the results on TV.
Peter Kinder, the vice governor of Missouri, wants to know what happened. Why no Guards, when they were all set to go? Did the word come down from the White House or the Department of Justice to keep the Guards out? Nixon didn’t answer, just accused Kinder of playing politics. (At least he didn’t play the race card, but that would be hard, white man to white man…. although it’s possible.) So we don’t know… yet.
