@Bart:
re: "TSOs don't stand to gain anything by "framing" a passenger."
And you know this how? The fact is, an obviously adulterated / incorrect test was done upon me, and the results of that nonsense test were used to move me to an isolated screening area, away from the general public. The person who did the adulterated test lied about it, and I was advised that all the cameras over the screening area were non-operational, and did not "see" the events that had happened at the screening area.

re: "the alarm was cleared and the passenger allowed to board the plane:" the alarm was "cleared" only when a second test was done in the presence of a police officer who had fortuitously volunteered to watch the second test, and who the TSA had no idea would be present for the second test. If the police officer had not volunteered to be present, I believe the second test would have been positive, then a search (sans police officer or any other non-TSA witnesses) would have been done.

Who knows what this search would have "found?" All I know is that the TSA was willing to perform a fraudulent test, and lie about it, and deny the existence of video evidence of their fraud. The immediate intent appears to have been to get me hidden away by myself in a closed room with them. What about this whole process seems benign to you?
