This argument is made irrelevant by the fact that the UK and other jurisdictions have rules of evidence which prevent the release of sensitive information from intelligence services [1] . There is no reason why playing a few minutes of recorded conversation in a courtroom automatically means that criminals and terrorists know the exact mechanisms used to record that information. Furthermore, if a trial is being held anyway, then the suspects involved already know that they have been monitored by intelligence services – otherwise they would not have been brought to trial. Similarly, high-risk terrorist cells already protect their communication by using things like encrypted messages [2] and disposable mobile phones [3] . Dangerous criminals and terrorists are already one step ahead of our current justice system; implementing this motion is the only way to have a genuine chance at apprehending them.
