FBI to Say Internet Thwarting Eavesdropping

The FBI is expected to reveal that because of the rise of Web-based e-mail and social networks, it's "increasingly unable" to conduct certain types of surveillance that would be possible on cellular and traditional telephones. FBI general counsel Valerie Caproni will outline what the bureau is calling the "Going Dark" problem, meaning that police can be thwarted when conducting court-authorized eavesdropping because Internet companies aren't required to build in backdoors in advance, or because technology doesn't permit it.
