Yes and no perhaps, or in this case, no, no and yes.

I do not, myself, hold a positive view of TSA based on my last passage through JFK, however:

I think a person behaving in a certain way, may attract the suspicion of security personnel and therefore should not be surprised when enquiries are made of him / her.

I think I agreed previously that, I also, did not condone their involving of the PD in this situation and to expand on that maybe they did not exercise the right judgemement but that's their call based on what the interaction actually was, I suppose. None of us were there. I suppose anyone can call the Police if they feel they see something suspicious and they will make their assessment when they arrive on scene. I also said that the OP must carry responsibility for instigated the scenario and expanding on that, fuelling it.

I would not, from what I have seen, like a body such as the TSA be given LEO status and it is right that at some point in the proceedings that if they are genuinley not happy they have to involve someone else i.e LEOs

I would be horrified if they actually had the power to strip search you, that I would not agree with. I don't know if they have it, I assume not.

So I partially agree with you but at the same time think the OP kicked it all off and should not have been surprised by the intervention!
