This is no laughing matter....this incident was a seditious violation of your Constitutional rights by the parties involved and you need to be proactive to make sure the TSA doesn't escalate this internally to the point where you end up on a watch list or are barred from flying outright.

Please contact the local ACLU before the media, and also consider addressing this with your own attorney if you have one.

Were there other witnesses to the TSA supervisor's comment about not having First Amendment rights at his checkpoint? At the very least he should be terminated outright and the officer involved in detaining you should receive additional training to better understand how to tell a real issue from a non-issue. At best, you might have a civil rights violation lawsuit against either or both parties.
