From Mashable --
The same day that Google is asking Congress to strengthen privacy protections for Americans' emails, the cops are arguing that U.S. law should require cellphone providers to store text messages logs in the event authorities need to read them in the course of a criminal investigation.
According to the proposal, backed by a coalition of law-enforcement associations, wireless companies like AT&T, Verizon, Sprint and T-Mobile would have to record and store customer's text messages for at least two years,
as first reported by CNET last year.
Richard Littlehale, a supervisor with the Tennessee Bureau of Investigation, testified this morning in front of the House Subcommittee on Crime, Terrorism, Homeland Security and Investigations, echoing the law-enforcement coalition's proposal. In his prepared remarks (

"Billions of texts are sent every day, and some surely contain key evidence about criminal activity," he said. "In some cases, this means that critical evidence is lost." And that's why he thinks cops should have a chance to go to cellphone providers and get their hands on old text messages if they need to, "with appropriate legal process, for at least some period of time."
Nowadays, data retention policies vary from carrier to carrier and there's no uniform law mandating the companies to store information for a determined amount of time. Companies don't publicize their data retention policies, but throughout the years, activists' and reporters have been able to piece together some scattered information.
In 2011, through a Freedom of Information Act request, the American Civil Liberties Union obtained
an internal Justice Department memo showing that as of 2010, AT&T, T-Mobile and Sprint didn't store the contents of text messages, while Verizon kept them for just 3 to 5 days, and Virgin Mobile for 90 days.
In 2011, Anonymous gained access to the Gmail account of a retired supervisor of the San Diego-based multi-agency Computer and Technology Crime Hightech Response Team. In an email received by the retired supervisor Alfredo Baclagan, and sent by Baltimore detective Rich Peacock, the latter discusses providers' data retention policies, confirming Verizon's and AT&T's policy and revealing differences with the rest. "Sprint stores their text message content going back 12 days and Nextel content for 7 days. [...] Us Cellular: 3-5 days Boost Mobile LLC: 7 days," reads the email,
published on Wired's blog Threat Level.
In his conclusion, Littlehale emphasized the importance of giving law enforcement access to information that can help track down criminals, as well as the importance of balancing that with people's privacy interests.
"Just as there is no question that people have an interest in preserving the privacy of that information," he said. "There can be no question that some of that information holds the keys to finding an abducted child, apprehending a dangerous fugitive, or preventing a terrorist attack."
