Britain’s most senior security official, Charles Farr, has been forced to comment on a UK government surveillance policy that exploits legal frameworks to monitor online communications. First revealed as part of the Edward Snowden leaks, Britains Government Communications Headquarters (GCHQ) has been reportedly intercepting and storing massive amounts of data flowing across the web, including emails and posts on social media sites like Facebook and Twitter. Farr has published a detailed justification (PDF) for the UK government’s spying program, dubbed Tempora, and defended the lack of individual search warrants which are normally required to monitor internal communications between British residents.
