But then I see something like this.

And then I saw this article by Glenn Greenwald concerning an American citizen who was tortured in Kuwait, then barred for re-entry in the U.S. for no good reason:

All of this underscores the rapidly expanding powers the U.S. Government and law enforcement agents within the country are seizing without a shred of due process. For the government to put an American citizen on the no-fly list while he’s traveling outside the U.S. is tantamount to barring him from entering his own country — a draconian punishment, involuntary exile, meted out without any due process.
