And I think that the fact that you can be on a no fly list as a suspected terrorist

Unfortunately, the people who have been put on the "no fly list" are there for stupid reasons.
Like buying Mein Kampf because it was required reading for their daughter's class.

This was found out after suing for disclosure. Wasting a ton a money.

A secret list, that has tens of thousands of people on it, most unknowingly, is not something for denying somebody their constitutional rights.
