Lawmakers take up government's ability to get old emails without a search warrant

"Google's law enforcement director, Richard Salgado, told lawmakers that provisions under the old law "do not reflect the reasonable expectations of privacy of users."

He also noted that the Justice Department has said there is no reason under privacy law for criminal investigators to treat old emails differently than newer emails. The Supreme Court ruled last year that law enforcement officers generally need a warrant to search the contents of a cellphone."
