I think this kind of reasoning just desperately tries to find reason in insanity.
You’re basically implying that the coordinated uncertainty is so incredibly good at being covert, that it’s absolutely indistinguishable from underpaid incompetence and power tripping pettiness.
Maybe I’m not giving enough credit to government agencies, but actual incompetence and artisanal pettiness seem to be more likely to me than a planned behavior.
I’ve always thought this was a fundamental floor in their logic. Since they don’t have bomb detectors at the entrances to the building, it’s all a bit irrelevant anyway since if I’m trying to take down a plane full of people I can blow them up just as easily in the airport as I can in the air.
They all collect together at the TSA line anyway.
