This is both enraging and hilarious, to be honest. A man named Kahler Nygard, who found himself inexplicably on a no-fly list 3 years ago, was approved to board a flight anyway and upon landing was asked to leave the airplane he was in– by himself — so that TSA agents could do additional screening on him at the arrival gate. This is already after he was searched once by the TSA. The TSA agents could not give reason nor could they detain him legally, so Nygard just told them he was leaving and walked out of the airport.

Kahler even has video of himself being screened correctly at his airport of departure.
