Says Department of Homeland Security Undersecretary Caryn Wagner:
Wagner said the department is establishing guidelines on gleaning information from sites such as Twitter and Facebook for law enforcement purposes. Wagner says those protocols are being developed under strict laws meant to prevent spying on U.S. citizens and protect privacy, including rules dictating the length of time the information can be stored and differences between domestic and international surveillance.Wagner said the Homeland Security department, established after the 9/11 attacks, is not actively monitoring any social networks. But when the department receives information about a potential threat, contractors are then asked to look for certain references within "open source" information, which is available to anyone on the Internet.The challenge, she said, is to develop guidelines for collecting and analyzing information so that it provides law enforcement officials with meaningful intelligence."I can post anything on Facebook, is that valid? If 20 people are tweeting the same thing, then maybe that is valid," she said. "There are just a lot of questions that we are sort of struggling with because it's a newly emerging (issue)."
