NSA Must Examine All Internet Traffic to Prevent Cyber Nine-Eleven, Top Spy Says

Ed Giorgio, who is working with McConnell on the plan, said that would mean giving the government the authority to examine the content of any e-mail, file transfer, or Web search. "Google has records that could help in a cyber-investigation," he said. Giorgio warned me, "We have a saying in this business: 'Privacy and security are a zero-sum game.'"
