Tony Lenehan has opened up about the David Campbell court case and answers one burning question - why he defends the accused21:05, 11 Aug 2026The defence lawyer for the 'Jekyll and Hyde killer' has opened up about murder trial as a new BBC documentary takes viewers inside the courtroom.‌Murder Trial is a hit documentary series giving viewers unprecedented access inside Scotland's High Courts as they witness real life court proceedings in real time. From examining witnesses to final arguments, viewers witness it all - and two new episodes have been released.‌Murder Trial: Death of a Dog Walker takes viewers inside the murder trial of 'Jekyll and Hyde character' David Campbell who was accused of killing ex colleague Brian Low. In 2024, Brian was found dead one winter morning by a fellow dog walker, but it was several days later it was revealed he had been shot.‌Available to stream on BBC iPlayer now, a synopsis reads: "Guilty or not guilty? Murder Trial, returns to the Scottish High Courts with the case of a man found dead in the middle of the countryside, with no witnesses, no forensics linking a suspect to the deceased and an accused man who the prosecution say has meticulously covered his tracks."Speaking to Reach PLC, Tony Lenehan defence KC revealed what it was like having cameras inside the courtroom as he opened up about the murder case that gripped the nation.‌As a veteran of high profile murder trials, Tony admitted there was one thing that has stuck with him from the trial: "Professionally I can't really comment on the personalities involved. But I think I would be allowed to say that there was a particular dignity about the widow of the deceased man, which was impressive in this case."However, Tony said this particular case was an unusual one with a "particularly uncommon story lying behind these events", which viewers will see play out in the programme.With a fairly straight forward trial, Tony added: "I don't think anything would surprise people from that point of view, but I think the events lying behind this were extraordinary."‌When it comes to the biggest challenges he faces in a courtroom, Tony said it would be having to strike the balance between providing witnesses with "sensitivity and respect" whilst at the same time "fearlessly defending whichever accused I have been sent to defend on that occasion."For some, it may be difficult to understand why someone accused of a serious crime would need representing. But for Tony, the answer is simple.‌He said: "You can do that because everybody deserves representation. If no one represented people in these difficult or unpleasant cases, then the risk of miscarriages of justice would be enormously higher. If people were forced to defend themselves then I am confident that witnesses would not enjoy the end result."With suspects appearing before the courts often being "poor communicators" or with mental health complications, Tony believes "abandoning them to speak for themselves doesn't sound like a route towards a robust system of justice."He went on to say: "It's not up to me to decide I think someone's done it. If there is very strong evidence in a case then part of my professional responsibility is to let the accused person understand that a trial is not the best way forward.Article continues below"So lots of cases don't ever go to trial, because either I or my colleagues assess the evidence and are able then to let the accused person understand that there is a better way forward for them, and that's by way of adjusted plea."However, there is one worry on Tony's mind, and that is how people view defence lawyers as he said: "My worry is that people come to it from a position of cynicism, thinking that the lawyers are closer to the accused people than they actually are and that the lawyers are purely the servants of the accused person rather than in fact being a servant to the court."Murder Trial: Death of a Dog Walker can be streamed on BBC iPlayer. Episodes will also air on Wednesdays at 9pm on BBC Two.
