I've been curious as to the procedures you can opt for during the screening process with regards to the 4th Amendment, among other things.

If I opt out of the AIT, as I will do from here on out, can I also opt out of the Enhanced Pat-down, and instead ask to go through the WTMD and the metal detector for my personal belongings?

I mean, the WTMD's should satisfy the inquiry of whether or not I have Weapons or Explosives, right?

I'd like to know more about what rights I do have before I get to the screening area (before I pass through the MD) and I'm in line, and what rights I have if I get moved over into a Secondary Screening area, and so on.
