As I reported here yesterday, the TSA does admit that some "screening lanes" were closed at various airports yesterday, but says this was because airport lines were running so smoothly.
On its blog crowing about how there were no protests yesterday, the TSA (oddly, it seemed to me) felt the need to also say: "Though volume was around expected levels, our preparations for today kept wait times at such a minimum that some airports are closing screening lanes due to a lack of passenger throughput." The TSA does not address which kind of "screening lanes" were closed.
But anecdotal reports, which first surfaced on Gizmodo yesterday are accumulating to support suspicions that the TSA might have roped off body-scanners, at least at some airports, perhaps in preparations for an "opt-out" protest that in fact failed to materialize.
Meanwhile, here's a video of a female passenger being patted down yesterday at the Houston airport. This is what to expect, for those who haven't yet had the new grope.
