The monthly "Airport Policy News" reports by Robert Poole, of the Reason Foundation, are a steady source of nuggets about economic, technological, and political developments in the aviation world. I would send a link to the latest report I'm about to cite, except that what's online, here, is routinely a few weeks behind what's come out in the newsletters.
I am not a full adherent to the Reason Magazine/Ayn Rand view of the world (I loved her books when I was 14, though!), including some specifics about aviation. But we are as one in dismay about the combination of authoritarianism, empty symbolism, and undiscriminating clumsiness that makes up much of our current TSA policy. See my Atlantic colleague Jeff Goldberg on this point too.
Poole's latest nugget is a GAO report on how the TSA is doing. Links to the full 75-page report and summary highlights are here. The cover page gets across the essential point, which is that years and years into its existence, the TSA is still not basing its screening plans, its strategy, or its technology on assessment of relative risk. That is, if you wonder why the two-year old in a stroller is getting the full pat-down and why so many TSA procedures fail the basic-logic test, it turns out that the GAO wonders those things too.
