FBI chief urges vigilance against cybercrime

FBI Director Robert Mueller visited San Francisco on Wednesday to warn of the dangers of computer-assisted crime and revealed that he had nearly fallen prey to an on-line scam himself. Asked whether the FBI investigates political dissidents in the guise of stopping terrorism, Mueller said the FBI intercepts phone calls and e-mails in the United States only with a court order - a wiretap warrant in a criminal case, and a surveillance warrant from a foreign intelligence court in a national security case. He didn't mention Bush's 2001 order authorizing electronic eavesdropping without a warrant in terrorist investigations, a program the Obama administration is now defending in a San Francisco federal court.
