I think some of the goals and methods of the occupy movement are wrong and immature but if the government can't link someone directly to terrorist or otherwise violent activity it should be criminal to put them on the no-fly list.
Mark Faulk was detained February 29th for 45 minutes for an "enhanced inspection" at Will Rogers Airport while trying to fly to New York for a film premiere. He was released in time to make his flight but they could have kept him as long as they wanted with no repercussions. His return trip was nearly identical even though he had been checked here. While the TSA refuses to tell Mark why he is on the no-fly list, his participation in Occupy OKC is the only thing that stands out. If a protester does something illegal it should be handled locally with criminal charges, not a federal "suspicious of being suspicious" list.
The no-fly list was established to stop known terrorists from getting on airplanes in the aftermath of 9/11/2001. If its purpose has migrated into a soviet style enemies of the state list who will be next?
If the simple act of protest has become an automatic terrorist indicator maybe it's time for all of us to join the next one. Freedom of speech and freedom of association were rights granted by God and then confirmed and protected by the U.S. Constitution.
