Data Mining on Facebook?

The Guardian has run a story on Facebook against the backdrop of the Ceop “panic button” proposal which reveals that the social networking site conducts algorithm-driven monitoring that “track[s] the behaviour of its users and flag[s] up suspicious activity.” OK, that sounds like data mining, but why is this story of relevance to counter-terrorism? Interestingly, the article states that "Facebook's international law enforcement is lead by Max Kelly, a former FBI agent who worked on cyber-crime and counter-terrorism before moving to Facebook five years ago." The article also discusses how Facebook interacts with law enforcement in the US and UK. It suggests that UK officials still feel Facebook doesn’t do enough to assist them and the UK public to protect the safety of children.
