ABA Journal Law News Now:  “A federal judge in Chicago has tossed a sheriff’s lawsuit against Craigslist that claimed ads for prostitution posted on the website created a public nuisance.  U.S. District Judge John Grady said Craigslist wasn’t legally responsible for the content, Bloomberg reports. Grady found that the company is protected by the Communications Decency Act, which shields providers of interactive computer services from liability, according to the Register. His Oct. 20 opinion (PDF posted by USA Today) cited a federal appeals court ruling finding the same law protected Craigslist from liability for discriminatory housing ads.”
