I'm not really sure where to put this thread, so feel free to move it to a more appropriate place... I visit Concurring Opinions about once a week and today was a bonanza! On the Colloquy: The Fourth Amendment and Airport Screening Issues The post goes over the 'special needs' doctrine. There's also a companion piece called 'The Bin Laden Exception'. It's good reading for all of us here. I'll probably be visiting the site a little more frequently as Susan Freiwald is guest blogging this month. She's a law professor at USF and focuses on the intersection of technology and privacy.
