[6] At about 5am on the morning in question Mr and Mrs Clay, who owned and occupied the house at 99 Cairns Terrace, were awoken by their dog barking loudly. Mr Clay, on looking from a window, saw in the yard of the house a person wearing a motor cycle helmet and dark jacket. Shortly after Mr Clay left the house and confronted that person. At that stage Mr Clay noticed that the person was holding a rifle. As he had previously served as a police officer Mr Clay had some experience with firearms and was able to give detailed evidence of what followed. Put very briefly, the person holding the rifle aimed it at Mr Clay on a number of occasions and pulled the trigger; there was a distinct clicking sound associated with pulling the trigger. The rifle did not discharge on any occasion. That was followed each time by the person holding the rifle operating the bolt action, which made a distinct noise, and again pulling the trigger resulting in a clicking sound with no discharge. Those noises associated with the operation of the firearm were also heard by neighbours who gave evidence, Summers and Attridge. Ultimately Mr Clay, who then had a rubber baton, tackled the person holding the rifle and held him down until police arrived. There is no doubt that the person holding the rifle and taken into police custody was the appellant.
