In the ongoing trial of law professor Diarmuid Phelan, jurors were invited to physically handle the Smith & Wesson revolver used in the fatal shooting of Keith Conlon on February 22, 2022. The prosecution aimed to demonstrate the pressure needed to pull the trigger, while the defense argued that Phelan acted out of fear during a confrontation with trespassers on his property. Phelan has pleaded not guilty to murder, claiming he fired to protect himself from threats. The trial examines key factors including gun safety and the circumstances surrounding the shooting.
