I accidentally upvoted you. There is the truth and there is falsity. None of our principles, including the one that says minimum wage security workers shouldn't be looking at us naked, mean anything if we can't look each other in the eyes and articulate them truthfully.
It is falsity that is allowing people to convince airport authorities that these machines make sense. If you want to get into the bullshitting arms race, know a priori that you will lose; those people are much better at it than you are, and they have more to gain or lose.
I'm not saying to lie. I'm saying if someone with credentials comes out and says there may be health issues with these things we don't need to look any further. They shouldn't be in the airport whether they present a safety risk or not. Instead of wasting energy chasing something that doesn't change the over all outcome (finding out they're safe still doesn't mean they should be used), use that energy to research things that do matter. It's just about being efficient. :)
