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."As the new series is released, Tony Lenehan defence KC has spoken to the Mirror's Screen Time team about the reality of having cameras inside the courtroom.‌Instead of camera crews on hand to film content, there are actually small remote operating devices placed around the courtroom. With it being unusual for viewers to see court proceedings on TV, Tony said: "In the build up to it I was particularly conscious of the fact that my role would be filmed."Well, the truth is probably within the first day you forget that the cameras are there because you're so focused on just doing the job that you ordinarily do."‌He added the way the cameras were set up were "not eye catching" in any way and there was no-one there to say "action", meaning everything viewers see was exactly how it played out in the courtroom.Tony admitted: "All of the court scenes are recorded from the trial. There's nothing that's staged or anything like that, all of the course scenes are 100% captured during a live high court trial."At the high court trial rather like any other, it's not as if we're trying to retake things it was just, this is a high court trial, which coincidentally, had these low profile cameras stage round about the court."Article continues belowWith the new release, there is one thing Tony hopes viewers will realise. He added: "I'm a strong believer in public justice, so the courts are run on behalf of the public, and so it's important that the public can have confidence in what happens in the courts."So steps like this, which bring the public into the courts for these important trials, I think are very important for the general confidence in the way we administer justice in this country."Murder Trial: Death of a Dog Walker can be streamed on BBC iPlayerChoose Daily Mirror as a 'Preferred Source' on Google News for quick access to the news you value.‌BBCDocumentariesTrue crime documentaries
