Even the strongest supporters of jury trials accept that sometimes juries get it wrong. Or, rather, the prosecution and defence cases and/or the conduct of the trial were so poor that the jury could not help but come to the wrong (guilty) verdict. So there is nothing wrong – if you believe that a miscarriage of justice has occurred – to campaign for its overturning. If people, including MPs, had not done this – many infamous miscarriages of justice (from Stefan Kiszko, to the Birmingham 6 to, most recently, hundreds of sub-postmasters) would have remained unchallenged. Nor is there anything dishonourable in standing by a friend. Unwise and insensitive maybe. But not necessarily dishonourable.
