The No-Fly list has gotten some renown both as an attempt to keep terrorists off of planes, and its ability to target people who are clearly not terrorists, to absurd levels like infants. Additionally, people aren't told when they're on the list until they try to fly, and they aren't told why they're on the list or how to clear their names. This has already led to lawsuits from American citizens who are prohibited from flying, including some that first found this out when trying to return to the US from other countries and being denied the ability to return home. 4 of the plaintiffs the ACLU represented were even US veterans (2 marines, 1 army, 1 air force). When the court was petitioned to let them return home, the US gov't allowed each to return to the US without ever disclosing why they were on the No-Fly lists to begin with. More recently, Al-Jazeera has run an opinion piece that looks at the No-Fly list in a greater policy, not just keeping people off of planes, but functioning as a tool to exile people, including some that are American citizens. In these cases, the government doesn't have to prove their case, they just are listing people without any requirement to disclose the evidence that leads to someone being on these lists, let alone proving that that evidence is substantial and should keep them from being allowed to fly. Additionally, for many of the people on these lists, who very often are directly from, or at least have family living in predominantly Muslim countries, being placed on the No-Fly lists keep them stuck in these countries when they return to visit family. They are then prevented from boarding a plane to return to the US, and without having had any case made against them or being told how to get removed from the list, they're effectively exiled. So, are these no-fly lists actually a necessary thing for the government to have? Additionally, should the government be allowed to keep this list in private, or should there be mandatory transparency, not just of who is on the list, but also why they are on the list and if that is justified?
