DHS claims that hundreds of thousands of people are too dangerous to allow on airplanes, but too innocent to arrest. There should be NO people who fall into that category! Yet this abomination has persisted for most of a decade, largely because of its secrecy.
There is a second, more secret list, which are people who TSA lets airlines board as passengers, but the airlines must secretly report to the government every time they appear in an airport.
Open up the no-fly list. This remnant of McCarthyism should either be public, and should be challengeable in public by the individuals listed, under the Privacy Act -- or should be eliminated.
Eliminate the surveillance list. The government has no business spying on the travel habits of hundreds of thousands of Americans -- without warrants!
There should be no place in a transparent America for a secret "enemies list" of people who by some secret process have been banned from exercising basic civil rights like moving from one place to another in the country. Or who are considered suspicious merely because they are moving from place to place.
