In the wrong place at the wrong time? You might end up on the no-fly list.
If you exercise your right to travel, will the US government use your past travel as the basis for denying you the right to travel in the future?

Merely having visited the “wrong” place at the “wrong” time (as subsequently and secretly determined by the precogs who devise the government’s algorithms for predicting future terrorist behavior) can be sufficient to get you put on the no-fly list.
Did you visit Yemen in 2009? Now you might be on the no-fly list — for that reason, and maybe that alone.
