can you phrase this paragrahp differently and make it shorter:In reference to section 78:"including the circumstances in which the evidence was obtained". This requirement to discourage the police officers/investigators from acting unlawfully. Evidence obtained legally or in good faith is less likely to be subject to a successful application under section 78 than evidence obtained illegally or in bad faith. Good or bad faith is particularly relevant to the issue of how the evidence was obtained. Bad faith on the part of police officers/investigators will usually lead to the evidence being excluded (R v Alladice [1988] 87 Cr App R 380). In Peters case the police officer acted in bad faith by influencing the ID parade. If a witness whose previous knowledge of the accused man has not made him familiar with his appearance has been shown the accused alone as a suspect and has on that occasion first identified him, the liability to mistake is so increased as to make it unsafe to convict the accused unless his identity is further proved by other evidence direct or circumstantial
