Yahoo Inc's secret scanning of customer e-mails at the behest of a US spy agency is part of a growing push by officials to loosen constitutional protections Americans have against arbitrary governmental searches, according to legal documents and people briefed on closed court hearings.
The order on Yahoo from the secret Foreign Intelligence Surveillance Court (FISC) last year resulted from the government's drive to change decades of interpretation of the US Constitution's Fourth Amendment right of people to be secure against "unreasonable searches and seizures," intelligence officials and others familiar with the strategy told Reuters.
