Technology & Marketing Law Blog by Eric Goldman:  “Judge John F. Grady of the Northern District of Illinois federal court dismissed Cook County Sheriff Dart’s lawsuit against Craigslist for user-posted advertisements in Craigslist’s erotic services/adult services category on 47 USC 230 grounds. This is hardly surprising, as I wrote in March that ‘this lawsuit is almost certainly preempted by 47 USC 230.’  However, it was nice to see such a clean and decisive opinion–and a little ironic, as our law enforcement officials, who are supposed to enforce the laws rather than bypass them, got schooled in the limits of their legal authority.”
