Didn't the news report that MI5 claimed that Scotland Yard and ISI were mobbed-up by jihadists? I believe that this was also one of Al Quiadas goals as well - to ask sympathizers to emigrate to western civilizations and enter positions of power and influence. So, being in spooky-world spooky things can happen... carefulness is advised - although aquiring people who know the middle-east is certainly imperative.
