Sorry, but my view is pretty much an anti-Governmental agency one. The folks at TSA are government employees. I suspect that, for the most part, the ones you encounter at the airport are low-pay-grade individuals, for whom the possibility of "power" may well be exciting!
I don't mean to demean
all government employees, but it has long seemed to me that those who most frequently have direct contact with the public are also the ones who delight in making life difficult for the public!
I frankly count my blessings that I almost never fly anywhere anymore!
