(CNSNews.com) - American government agencies – state, local, and federal -- made a record 13,753 requests to read emails or gather other information sent through Google’s Gmail and other services in 2012, more than half without warrants, according to statistics released by Google.



The total number of users about whom government agencies wanted information also set a record at 31,072, up from 23,300 in 2011, the first year Google began reporting the data. The discrepancy comes because government agencies request information on multiple users or accounts at the same time.



Most of these 13,753 requests, 6,542 of 8,438 in the latter half of 2012 alone, were done without a search warrant, Google data show. Google did not make available any detailed data prior to June 2012, nor did it make available which requests came from the federal government and which came from state or local law enforcement agencies, when asked by CNSNews.com.



Google spokesman Chris Gaither said the company only started tracking which type of legal authority – subpoena, court order, or search warrant – was used in the latter half of 2012. Google issues biannual reports on the requests for user data it receives from government agencies from around the world, including ones in the U.S.



Google announced in June 2012 that it had 425 million active Gmail subscribers, making it the largest e-mail provider in the world. It also provides users the ability to store documents via its Google Drive service, phone service via Google Voice, YouTube, personal blogs via Blogger, as well as email hosting services for corporate clients through Gmail.



Google keep records of all email and other communication sent through its e-mail, telephone, YouTube, and other services, storing the information on cloud servers – a move that allows government agencies, local, state, and federal, to access some information without a warrant.



Federal law allows government agencies to access Google’s archived email and other data, including chat logs, YouTube user information, voice messages, and blogger information without obtaining a search warrant or establishing probable cause, and Google says that it complies with the vast majority of government requests for data.



From July-December 2012 Google provided user information in 88 percent of cases. From January to June 2012, it provided information in 90 percent of cases. Those figures were down from 2011 when it provided user information in 93 percent of cases.



The government can access data, including the content of emails sent or received through Gmail, because Google keeps records of all communications sent over its various services and stores the information on cloud servers, lowering the legal threshold government agencies need to access some of the data, including the name, Internet address, and telephone number of Gmail, YouTube, and other Google users.



The federal law that allows this is known as the Electronic Communications Privacy Act (ECPA) which says that opened email stored remotely – not on a computer’s hard drive – can be accessed without a warrant.



If the government wants to read the content of an email accessed through Gmail, hear a voicemail message sent over Google’s telephone service Google Voice, or read other private content, it must still obtain a search warrant under federal law.



However, information not sent in the body of an email or recorded in a voice message can be obtained by a simple subpoena – which does not require a government agency to show probable cause. Such information includes the name of an e-mail account holder, the IP address used when signing into and out of Gmail including dates and times, and other information you gave to Google when you created Gmail or other Google account.



Other types of information require a court order from a judge, such as the IP address of a particular email, email addresses of those you correspond with, and the web sites a person has visited.



A search warrant is required to read the content of an email stored on Google’s servers, as well access as internet search histories, YouTube videos, photos, and other documents.



Because all types of requests usually come through some kind of criminal investigation, Google does not notify users when the government demands to read their emails or access their account information. However, Google says that in cases where it is legally allowed to inform users, it tries to do so.



“We notify users about legal demands when appropriate, unless prohibited by law or court order,” Google says on its transparency website.

“We can't notify you if, for example, your account has been closed, or if we're legally prohibited from doing so. We sometimes fight to give users notice of a data request by seeking to lift gag orders or unseal search warrants.”



Google says it requires government agencies make a formal, written claim under ECPA before it will release any user data.



“The government needs legal process—such as a subpoena, court order or search warrant—to force Google to disclose user information. Exceptions can be made in certain emergency cases, though even then the government can't force Google to disclose.”
