Basically don’t act like a weirdo in the airport (or like a normal person) because air marshals may be following you and documenting everything you do in hopes of discovering you’re up to no good.
That does seem concerning.
Of course the side of it is that the stakes are high. We don’t want bad people to be able to hijack planes and ram them into who knows what and kill who knows how many people.
Just as good an excuse to follow random people around anywhere and document everything they do…just in case they murder, rape, or rob.
Seems a really inefficient and ineffective way of spotting wrongdoers.
It’s not like they already don’t have a touchy-feely TSA, extensive baggage screening, and other security measures in place. Look at the behaviors the air marshals are supposed to be tracking. It’s total nonsense.
For years now it’s been reported - here and here for example - that the air marshals are a waste of money. I think this program has been an attempt to justify the cost. Really it only emphasizes what a fruitless program it is.
