Ted Kennedy flagged by no-fly list
How easy would it be for a CIA agent who hates kennedy to add that name to a list? So so easy. If they found a terrorist cell's hideout all you'd have to do is take out a piece of paper and write "aliases" on top of it, put a few real ones used by terrorists, make up a few like j. smith, and then put t. kennedy on the bottom.
That's why giving the cia/fbi the power to deny people the right to fly based on secret evidence or no evidence is wrong.
