Intercept evidence is simply not reliable enough to be effective evidence in court.  Wiretap evidence is not as reliable as other forms of evidence which we currently have at our disposal, such as DNA evidence which has ‘sent thousands of people to prison and . . . has played a vital role in exonerating men who were falsely convicted’ [1] . Many potential aspects of intercept evidence lack this reliability. Voice analysis, for example, has been shown to be unreliable in exploring messages supposedly spoken by Osama Bin Laden [2] . Video intercept evidence notably failed when a video which purported to show Morgan Tsvangirai (the Zimbabwean opposition leader) conspiring against the government, when in fact he was somewhere else at the time [3] . The poor quality of intercept evidence is a threat within an individual trial, but also more widely; reliance on intercept evidence by prosecutors might lead to more cases collapsing after the evidence is proved unreliable, and wasting time and money for all involved.
