The FBI and other law enforcement agencies have gotten more and more hungry for Google users’ data over the past four years. Google said on Thursday that requests for users data from the United States government have more than tripled since 2009, going from just under 3,600 in the second half of 2009 to more than 10,900 in the first half of 2013. And America isn’t alone in asking Google for more data: Worldwide requests have more than doubled from 12,500 in the second half of 2009 to 25,900 in the first half of 2013. Google’s most recent update on user data requests still doesn’t have any details on the requests it receives via the Foreign Intelligence Surveillance Act because the American government has barred it from disclosing details on FISA-related activities.
