I like your attitude of "really no harm was done" in our over-litigious society. Still, it might be worth a letter to TSA because the screeners' conduct appears to be outrageous. Like all government bureaucracies, TSA has a "civil rights" office (it might be at the DHS level, although TSA does have an office for matters related to screening of passengers with disabilities), and complaints about "civil rights" (in your case, it would be based both on age, because of the comment about people your age not having pacemakers and on disability or medical condition) go right to the top of the list for attention, trumping all of the other legitimate complaints about just plain rude and thuggish behavior from screeners.

To answer another question of yours, the screeners are employed strictly by TSA, so are fully unaccountable except by our political process.
