Dan Drezner, with whom I often agree, and Megan McArdle, with whom I sometimes agree, unite in opposing the new scanning/pat down procedures at some airports. Kevin Drum passes on an apropo observation--this is the professional class being subjected to "government[al] humiliation".
Bottom line--people arrested for good cause, or not so good cause (i.e., driving while black) get subjected to such patdowns and none of us professional types have much problem with that.
I'm assuming the use of these scanners increasing the likelihood of detecting people with explosives in their underwear. I'm also assuming we believe it's a good thing to keep people with explosives off airliners. People who object presumably have persuaded themselves there's no increased detection ability, or possibly they would never be so unlucky as to be on a plane with a fellow passenger who has explosives. Or maybe they're just reacting with their emotions, and not their logic.
