I work for the TT ground handler and every other week this is happening. Any lighthearted or passive comments which can be perceived as a threat are now taken seriously. They were, before, obviously, but things have gotten extra serious. Two weeks ago, before door-close, we offloaded a group of boys' boys with tattoos on their faces making lad jokes, referencing some movie they had watched in which there was a "hijacking". Cabin crew overheard it, then told me, as ground liaison, and we had to inform the Captain. "Get them off," he said, instantly. No hesitation or further enquiry. When the federal police arrived, all passengers in the vicinity refused to make witness statements, saying it was just a joke and wasn't that serious, and that they'd seen the movie the boys were joking about - and also that they couldn't believe the boys were being offloaded over something so trivial.
