I understand you were threatened but I also believe that TSA was wrong, possibly criminally wrong, in their actions. They can't just put you on a watch list for doing something that is perfectly legal. Even TSA says what you were doing was ok.

Will you never fly with your lifesaving medicine again?

I don't wear your shoes but I would make it a point in challenging TSA on this point. I would start with a complaint to the DHS OIG with a copy to both of your Senators. I would even consider filing a complaint with the ADA. http://www.ada.gov/filing_complaint.htm

I would routinely take the pills, although perhaps only a bare minimum, and hope that TSA would do something stupid again and if they did I would file a complaint with the local police then and there. I would try to involve the TSM for that terminal and get as many names as possible and then I would contact the consumer advocate from a local TV station. A news spot, "TSA tries to kill passengers" more at 6 PM would do more to fix this than anything else.

You were not in the wrong to take your medicine. You have every right to do so. Don't let these TSA GED Commando's put you in a position of not having your medicine when it is needed.
