of Dryden's gun. The camera pans to Dryden, who fires the gun at Collinson (now off-screen). As everyone (including crew) disperses, Dryden shoots and wounds the police officer and the reporter. A fuller version of the footage, including a prior visit and the aftermath of the shooting, now forms part of the BBC's filming safety internal training course. A subsequent search of the property and Dryden's home at Priestman Avenue, Consett, uncovered 10 handguns, 15 rifles, three shotguns, two homemade mortars with eight projectiles, an improvised propane bomb, and a 20mm cannon modified to be attached to one of his vehicles. Dryden had no firearms licence, and all the weapons were illegally held. Following the murder, it became known that Collinson and Dryden had previously enjoyed a friendly relationship, with Collinson regularly visiting the Eliza Lane property to advise Dryden on planting trees for screening and what type of building work was permitted. However, Dryden's increasingly bizarre behaviour, his decision to dig a deep trench in which to build the bungalow with just the roof showing, and his threats towards—and physical assaults against—council staff brought the men into conflict. It was also revealed that the council had wanted to visit the site under cover of darkness to carry out the demolition, when Dryden would have been asleep at his home several miles away in Consett; Collinson disagreed with this underhand tactic and insisted that their actions should take place during the day and in the presence of the media to avoid any allegations of inappropriate conduct. Collinson also did not expect Dryden to back down, and arranged for a camera crew employed by the council to record the confrontation, which would allow the council to retreat without demolishing the building, instead passing the footage to the High Court to allow them to deal with the matter. Trial Dryden was tried at Newcastle upon Tyne Crown Court convened in the Moot Hall in March 1992, charged with murder; the attempted murder of Belmont, Campbell and council solicitor Michael Dunston; and an alternative charge of wounding Belmont and Campbell with intent to cause grievous bodily harm. Dryden entered pleas of not guilty to all charges on the grounds of diminished responsibility. After 13 days of evidence, the jury took just two hours of deliberation before finding Dryden guilty of Collinson's murder, guilty of the attempted murder of Dunston, and guilty of wounding
