The NY Times reports that Robert S. Mueller III, the director of the Federal Bureau of Investigation, traveled to Silicon Valley on Tuesday to meet with top executives of several technology firms, including Google and Facebook, about a proposal to make it easier to wiretap Internet users. Mr. Mueller wants to expand a 1994 law, the Communications Assistance for Law Enforcement Act, to impose regulations on Internet companies. Under the proposal, firms would have to design systems to intercept and unscramble encrypted messages. Services based overseas would have to route communications through a server on United States soil where they could be wiretapped. An interagency task force of Obama administration officials is trying to develop legislation for the plan, and submit it to Congress early next year.
