According to RT (previously Russia Today), under the Homeland Security rules, the National Operations Center Media Monitoring Initiative allows NOC to capture and store information on journalists using traditional and social media sources. The directive allow collecting information that:
“permits the identity of an individual to be directly or indirectly inferred, including any information which is linked or linkable to that individual.”
The new rules are a deviation from previous policy that required written authorization. RT notes that the new policy coincides with efforts by journalists who have reported on Wikileaks to prevent their Twitter accounts from being provided to federal prosecutors. RT also notes that the Boston Police Department and the Suffolk County District Attorney are trying to gain access to information from Twitter on people who had made certain posts about Occupy events.
