Exbayern provided me with advance recon about LHR, which proved to be mainly accurate, as it was far less intrusive than TSA. I was at terminal 3, where they use WTMD exclusively. According to Exbayern, they have scanners for secondary searches, but I didn't see them. For men, it was pretty much like pre Black October 2010, you put belts, carryons, jackets in the buckets, but of course, not being the USA, no shoes had to be removed. For the women, the machines were set to such a low thresholds that they invariably alarmed, my guess is probably the wire in the brassieres. Unlike rational countries like New Zealand, which resolved this by hand wand only, each woman who alarmed was taken just next to the WTMD so it could continue being used (several carry-on scanning queues fed into a single WTMD). Then the usual breast area check, just like TSA does it, gotta make sure everything is real, no boob bombs. But because they don't bother hand wanding, the idiots then check everything else, arms, back, waist, running fingers around the belt but doing absolutely no swab tests. They use front of hands but don't have the person turn around to check their backs, the clerk simply reaches around the person being searched as if embracing them to feel their back and their butts with the front of the hands. It really is obscene looking, like they are having a make-out session. Only marginally better than the rubbing TSA does. (yes, same sex searches only). Then the usual up the leg check, but not going as far as the TSA does, no touching of private parts although they do feel alongside the front of sensitive areas (a few inches outside the zipper), basically like the old frisk used to do. Nearly every woman I saw there had to endure this. There was only one female clerk there, so when she was occupied, the TMD gatekeeper told other arriving women to stay put: "gents only please". This struck me as quite stupid on the part of the Brits. You know why most of these alarms occur, why not at least hand wand to determine location. then a light check just in that area to see if there's anything untoward. Or better yet, do as the New Zealanders do, confirm location and let 'em through. It's almost as if they're using this as an excuse to feel over all the women, but from the look of the female screener, not a desired activity. She looked very embarrassed. The Brits get very low marks by the way they handle such an expected and common occurrance. My guess is that the TSA is putting them up to this. I had to laugh at the secondaries at the gate for my flight. My airline had two lines going into the gate, the upper class/premium line where I went in, and the economy line where the bulk of the people were. Inside the gate was a table with a clerkette, and a clerk with a turban staring intently at the ECONOMY LINE ONLY (evidently terrorists don't fly upper class, or more precisely, in a class-driven society like Britain, that simply wouldn't do). He would make a selection, then the winner would come in, dump the contents of his carryon where the clerkette inspected it whilst the victim was felt over. Usual arm feel over, chest butt and back feel over, but not quite as offensively as TSA does it. Fingers along the waist band but no swabbing. I guess that part of the theater always ended badly, so they don't do it. Hands up the legs but not as far as TSA, doesn't get near the crown jewels, front crotch a few inches from the zipper alongside it, the old frisk style. So there you have it. Use of WTMD good, use of stupid protocols to resolve common women's clothing, bad. Fly upper class or economy premium and perhaps bypass the gate check.
