What has happened to other pax who have claimed, falsely, to have a bomb in their luggage or uttered other provocative statements. They have been removed PDQ and interrogated. What has been the follow up regarding punishment of them. This would seem to fall into the same, or even worse category. I doubt the numpty pax left home with a complete pre-mediated disruption plan; these guys did. If they caused disruption that resulted in delayed flights and other pax missed their connections etc. the lawyers on their behalf would have a field day suing for compensation.
