Why the hell do these tin-star bullies get their own initialism? A TSA officer or agent or whatever is not called a TSA agent or a TSA officer or a TSA groper. No! A TSA agent is a TSO (a Transportation Security Officer).
CIA agents aren't CIOs.
FBI agents aren't FBAs or FBOs.
But the heros of the TSA get their own, special designation.
Now they are really gone too far!
I think that part of the TSA problem is that they want to be more important than they are. "Claiming" a title like officer, perhaps hinting to something like police-officer, will or might give them more authority with the average public.
