Sir Malcolm Rifkind, the chairman of the British Parliament's intelligence committee, has defended the practice of using bulk email data to track terrorists. He said that it is worth giving up this individual liberty in order to remain secure. He also pointed out that most emails aren't read by humans but by computers. Rifkind's comments come in response to eight Internet companies that are asking the US government to reform its process of collecting bulk data via emails. These companies - Google, Apple, Facebook, Twitter, AOL, Microsoft, LinkedIn, and Yahoo - have formed an alliance called Reform Government Surveillance.
