This is a print-length back and forth between Richard Posner and Geoff Stone, two Chicago law school profs, on the balance of civil liberties and seecurity in the U.S. specifically around the Patriot Act. The analyses are top notch and it teaches me a lot about deconstructing another’s argument. Finally, it is very entertaining and often laugh out loud funny, especially when they trade hypotheticals – would it be justified for a police officer to punch a kidnapper in the nose if he tells where the victim is? What about tying electrodes to his testicals? Where does it end? Also, good thoughts on the ACLU.
