More established forms of evidence – even those as sophisticated as DNA testing – also have their weaknesses. Following the death of British student Meredith Kercher, her supposed killer Amanda Knox was imprisoned after DNA evidence proved that Knox’s DNA was found on the handle of the murder weapon (a kitchen knife) while Meredith’s blood was on the blade [1] . However, an appeal has declared that the DNA evidence ‘was so small it should have been considered “inadmissible”’ [2] , and the original forensic team have been branded as incompetent [3] . This is an example of an extremely high-profile case which hinged a conviction on the use of ‘reliable’ DNA evidence, and may potentially be proved wrong – the appeal is currently ongoing. There is no evidence which is utterly, 100% certain; it is always open to interpretation. However, allowing intercept evidence in court gives another chance at finding out the truth. Given that intercept evidence would work in combination with expert cross-examination, there is no proof that intercept evidence cannot be as effective as any other form of evidence – or perhaps even more so.
