The Ninth Circuit Court of Appeals ruled yesterday in support of airport regulations demanding the display of identification by travelers — and in support of the existence of secret laws, laws that our government can prohibit people from scrutinizing yet can impose on those same people. (The decision, in PDF form, is here.) As reflected in my feelings back when the case (Gilmore v. Gonzales) was being argued, this is somewhat disappointing; it seems perfectly contrary to the ideals of our country for there to be laws whose words exist behind lock and key, but whose force exists in the lives of each of us.
