I havn't had the chance to listen to the call-in from FTL, but I was weary of these things as soon as I heard they used X-Rays.  I remember hearing stories about how small x-ray machines were used to find out shoe size in the 1940s/50s.  It was discovered that this exposure was dangerous, and they were removed. 

Now you have full body scanners emitting radiation on you, and if you fly alot, you get quite a dose.  There was a letter of concern posted by 4 Ph Ds. on NPR explaining the possible medical dangers of these things.

If you know anything about radiation, gamma rays with higher penetration are generally safer. Alpha and beta waves do not have much penetrating ability and can be shielded easily.  Higher penetration in gamma waves is safer because the rays pass right through without much interference.  However, these x-ray machines use low energy waves, so the skin and nearby tissue ends up absorbing the radiation.  This is how they get skin level type of x-rays. 

It is also no surprise that these doctors are saying the testing on these products to determine dose is misleading.

I've commented some on the wewontfly story about smeg (as iawai), and I've come to an unfortunate conclusion.

There is a slew of new comments from "weekly fliers" and others who whole-heartedly love the scanners and do nothing to support thier position but suggest opposition is "stupid" and the procedures aren't bad because they don't limit liberty anyway (e.g. "so just don't fly").

These are not random internet travelers happening upon a story from some aggregator, at least not all of them.  These are carefully crafted, short and dismissive, and pro-government force couched in snobbish and happily complying language.

One such post was by a poster named "Hal Turner" - Hal Turner November 10, 2010 at 8:46 am

Id rather a professional look at a very un-detailed picture of my body than getting blown up in a plane. This website is so stupid its unreal.

Who is Hal Turner? via wikipedia:Harold Charles "Hal" Turner is an American white nationalist and white supremacist from North Bergen, New Jersey. He was arrested in June 2009 for threats which he made against three federal judges with the 7th U.S. Circuit Court of Appeals. Prior to Turner's arrest, his program, The Hal Turner Show, was a webcast from his home once a week.

Turner promotes antisemitism (including the rounding up and killing of Jews),[1] opposes the existence of the state of Israel[1] and denies the Holocaust.[2]

Further:

Turner was a paid FBI informant for several years, supplying information about right-wing groups to federal agents.[23] The original allegations that Turner acted as an informant for the FBI surfaced in 2008 after unidentified hackers claimed on Turner's website's forums that they had read email correspondence between him and an FBI agent, apparently his handler.[24] This led to a discussion on a neo-Nazi website on January 10, 2008, in which Turner revealed he was quitting political work, was ending his radio show and that he was separating "from the 'pro-White' movement".[24] The FBI has declined to comment on the matter.[24]

So, unfortunate coincidence in name, or targetted, gov't sponsored attemt to discredit anti-TSA activists?

I hate to buy into conspiracies without proof, but this really stinks.  Thought I'd share this little theory here, off the wewontfly site, just to set a paper trail in case there are more incidents of fishy "counter information" being spammed to stories, blogs, or forums that are potentially devastating to the National Socialist Security goals.
