Or to put people on "watch lists" or whatever. There's never been any public information on how names make it on to the "No Fly" list, or the "Special Search List" for air travel.

And there we plunge off the cliff into another un-American idea: the government can allow petitions for redress of being put on a "No Fly" or "Search Real Good" list, but it can't act on them: both method of determining reason, and the evidence of reason for being on the list don't hold up to reason. The government might allow petition for redress, but it can't effectively redress that greivance. Completely un-American.
