"I think I know the answer...because it's a political list that anyone can be added to for any reason, with no recourse or appeal."
I'm sure there's also suspected terrorists with un-actionable evidence against them in there, too. It's a big list, plenty of room for every one.
"1. Who maintains these lists?
2. What criteria gets you on the list? Can you be put on one of these just for sending an angry letter to the White house (non-threatening of course)?
3. Why can't your average citizen see these lists? Who IS authorized to see them?
4. If you do find out that you are on one of these lists (usually by being denied a boarding pass at the airport), how do you go about getting your name OFF of the list?"
1) I believe it's a joint thing by the various conglomerated fourth-branch bureaucracies ('agencies') that make up Homeland, and probably part of the reason it's so hard to appeal your place on the list
2) I'll have to try and find where someone posted it here recently, but back in 2005 or so there was a big, long document that purported to publicly disclose the criteria for the Suspected Terrorist Watch List, oversight, appeals process, people responsible, etc. Bear in mind the list had operated with this information completely classified from the public for two years prior, so forgive me for rolling my eyes when the feds claim that they are stridently adhering to what is in the publicly-available document without independent oversight or secret procedures. I do know the document clearly stated that a person whose terrorism charges have been dismissed will be added; guilty until proven innocent, guilty if proven innocent
3) Federal law enforcement bureaucrats, is my understanding (I'm sure local law enforcement can ping the list through federal contacts, but my understanding is they can't 'browse through it' so to speak)
4) Your only recourse is pleading with the same faceless bureaucracy that put you on the list in the first place. No formal court-based proceeding was mentioned in the 'appeals' process I skimmed through, just making toothless requests through agency contacts (probably starting with your local Homeland or LEO folks and working upward, apparently over the course of several years if reports from those who successfully got removed are to be believed). Why bother, though; you'll just end up on some even more secret list of people who managed to get off the Watch List (it's probably called the "Watch Closely List")
Just a variation on the old cringeworthy pro-gun bumpersticker;
"I remember this one movie where the government kept lists; it was called
Schindler's List"
