Which is what the no-fly list effectively is. It's opaque, the criteria for getting on it are buried in bureaucratese, the actual process by which a person was placed on the list is "classified", and appeals, such as they are, are usually done internally in the TSA/DHS apparatus. The normal system of American law enforcement and punishment is a split and open model, in which the Legislature writes laws which are publicly published, the Executive enforces/prosecutes under these laws, and the Judicial Branch interprets the laws and supervises trials (In which defendants normally have a right to a public trial by a jury of their peers). In the "No-Fly List" system, the Legislature provides a vague fig-leaf of a law that effectively gives the Executive so much interpretive power that it is pretty much capable of writing its own law. The Executive then controls the agents which enforce the law, AND controls most of the people hearing the appeals, AND cloaks the entire process in secrecy.
Sad how many people are so fixated on the issue-du-jour, currently "OMG GUNZ AND TERRAH," that they are now braying approval for a system of policing which is deeply antithetical to open and transparent government. Democracy isn't very effective at controlling the government when the people are legally prohibited from learning about what the government is actually doing. How many of the same people demanding Common-Sense Solutions in threads like this would support a NO TERRORISTS IN WOMEN'S HEALTH CENTERS ACT? Imagine, a law which makes it a felony for anyone on a terrorist watchlist to enter a Planned Parenthood. A few years ago, that would have meant that some nameless Bush stoolie could have effectively made it a crime for any woman to enter a clinic, and all that this woman could have done would have been to appeal her watchlist status to some other Bush stoolie, who could then claim that the entire process was classified and that it would threaten national security to openly disclose the criteria by which that woman had been watchlisted.
