FBI turning to social Web sites to fight crime

OUTREACH PROGRAM US agents have been using fake personalities on social networking sites to catch suspects, contravening the rules of some of the sites

THE GUARDIAN , WASHINGTON

Any criminals dumb enough to brag about their exploits on social networking sites have now been warned: the next Facebook “friend” who contacts you may be an FBI agent.

US federal law enforcement agents have been using social networking sites — including Facebook, LinkedIn, MySpace and Twitter — to search for evidence and witnesses in criminal cases, and in some instances, track suspects, a newly released US Department of Justice memo says.

FBI agents have created fake personalities — in apparent contravention of some of the sites’ rules — in order to befriend suspects and lure them into revealing clues or confessing, access private information and map social networks.

LAWSUIT

The new online efforts were revealed in a justice department document obtained by the Electronic Frontier Foundation, a San Francisco-based legal advocacy group.

The document, a 33-page slideshow prepared by two justice department lawyers, was obtained in a lawsuit the group filed against the department, seeking information on its social network policies.

Law enforcement agencies have long used internet chatrooms to lure child pornography traffickers and suspected sex predators and, with a warrant, can seize suspects and defendants’ e-mail records.

However, Facebook, MySpace and other social networking sites provide a wealth of additional ­information, in photographs, status updates and friend lists.

In many cases, the information is publicly accessible.

In a section entitled “utility in criminal cases,” the document says agents can scan suspects’ profiles to establish motives, determine a person’s location, and tap into personal communication, for instance through Facebook status updates.

CHECKING ALIBIS

Agents can examine photographs for guns, jewelry and other evidence of participation in robbery or burglary, and can compare information on Facebook status updates and Twitter feeds with suspects’ alibis.

Friend lists can yield witnesses or informants.

The document advises agents that Facebook is now used in private background checks. It indicates that Facebook often cooperates with emergency law enforcement requests.

In one section on working undercover on social networking sites, the document poses but does not answer the question: “If agents violate terms of service, is that ‘otherwise illegal activity?’”

Facebook rules bar users from providing false information or creating an account for anyone other than yourself without permission, and says that users should “provide their real names.”

RULES NEEDED

Marc Zwillinger, a former US cyber-security prosecutor, said federal investigators working online should be able to go undercover as much as they do in the real world, but said rules need to be developed.

“This new situation presents a need for careful oversight so that law enforcement does not use social networking to intrude on some of our most personal relationships,” Zwillinger said.
