Factual background
10 At trial there was little dispute as to the facts. Significant admissions were made by both offenders in the course of the trial. The following facts would seem to be uncontroversial.
11 On 27 March 2002 Senior Constable McEnallay was driving an unmarked police patrol car in Bunnerong Road, Matraville. Near the intersection with Military Road he observed a green Holden Commodore sedan, registration No AJK 32M. The possible presence of this vehicle in the area had previously been reported to him by an off-duty police officer, Constable Deitrich, who had seen it at about 5.30 pm travelling at speed and somewhat erratically, in Botany Road, Matraville.
12 Senior Constable McEnallay asked for a vehicle check to be made and was advised that it had been reported as stolen. He followed the green Commodore in Botany Road and then right into Beauchamp Street. The two vehicles stopped at the lights controlling the intersection of Beauchamp Street and Denison Road. In the meantime he had asked for assistance from other vehicles, and had also requested the driver of a caged police vehicle, which was in the area, to drop back as he did not want the occupants of the green Commodore to be aware that they were being followed.
13 In Denison Street, at about 5:51:50 Senior Constable McEnallay activated his siren and lights announcing his pursuit of the green Commodore, which made a right hand turn at speed into Grace Campbell Crescent. On attempting this turn the vehicle struck the gutter, or a traffic island, and came to a stop at about 5:52:10, as a result of damage occasioned to a wheel, which effectively immobilised it.
14 At this stage Penisini, who was armed with a .38 Smith and Wesson revolver, exited the green Commodore and immediately fired five shots, in quick succession at the driver side window of the police vehicle which had come to a stop about 10 metres away. Senior Constable McEnallay, who had been unable in the time available to draw his own weapon, or to seek a position of safety, suffered gunshot wounds to the chest and head which led to his death, seven days later on 3 April 2002.
15 Penisini, along with the other occupants of the green Commodore, who included the appellant and John Taufahema, ran from the vehicle in an easterly direction, through some units in Neilson Avenue and Grace Campbell Crescent. On their way, Penisini dropped his revolver and a pouch containing a number of .45 calibre and .38 calibre cartridges, on the footpath outside 9 Grace Campbell Crescent. The appellant was seen to drop his weapon, a .38 Smith and Wesson revolver, in the garden of 12 Grace Campbell Crescent on his way to a residence at 5 Rhodes Street, where he managed to hide from the police, in a laundry, for several hours, before eventually making his way home. Before doing so, he exchanged his clothes for clothing which he found in the laundry. He was not arrested until 3 April.
16 John Taufahema and Penisini also made their way towards Rhodes Street. They were pursued on foot by Senior Constable Day and Constable Kolosque. While moving through the small area of park, which runs between the premises at 7 and 9 Grace Campbell Crescent respectively, and up a hill to Rhodes Street, John Taufahema presented his hand gun, a .38 Smith and Wesson five round revolver at Constables Day and Kolosque and threatened to shoot them if they did not back off.
17 Both officers maintained their pursuit. They had drawn their own service weapons and repeatedly warned Penisini and Taufahema to stop and to drop the revolver which Taufahema was holding.
18 When they reached Rhodes Street, Penisini and John Taufahema made their way north, still pursued by Constables Day and Kolosque. A motor vehicle driven by Lamia Kassis was observed to be slowing for a speed bump. John Taufahema made his way to the driver's side of this vehicle and pointing his weapon at Ms Kassis instructed her to get out of the vehicle. She complied with his request. In the meantime, Penisini attempted to force his way into the front passenger seat.
19 At this point Constables Day and Kolosque caught up with the men and began to struggle with them. Senior Constable Day attempted to subdue Penisini and eventually did so, after hitting him over the head with his service pistol and spraying him with capsicum spray. Constable Kolosque fought with John Taufahema who was still holding his handgun and pointing it at the two officers. They struggled over the ignition key and at one stage Taufahema managed to get the vehicle into motion but it moved backwards striking a vehicle behind it.
20 Eventually John Taufahema was overpowered by Constable Kolosque with the assistance of Senior Constable Day who had come to his aid, although not before being struck on the head several times with the butt of a service weapon, and also being sprayed with capsicum spray.
21 In the meantime Penisini, who had been sitting for a while on a fence, no doubt still affected by the spray, had moved away from the vehicle into the park to the east of Rhodes Street. He was pursued by Senior Constable Day and with the assistance of Constable Rowbottom, who had also come to the scene, was arrested in that park. The revolver of John Taufahema was recovered from the vicinity of Ms Kassis' vehicle.
22 For completeness it should be noted that the other occupant of the green Commodore was one Motekiaa Taufahema. He was apparently the driver of the vehicle. He also ran away from it when it became disabled. He was arrested in the rear yard of premises at 31 Rhodes Street moments after the arrest of John Taufahema and a .357 Magnum six-chamber revolver, which he was seen to drop in the garden of 33 Rhodes Street, was recovered in that location. There is otherwise no need to make further mention of Motekiaa Taufahema.
23 A search of the green Commodore revealed that it contained gloves, hats and an ice-hockey mask, items capable of being used as disguises. The weapons of the appellant and John Taufahema were fully loaded but had not been fired during the relevant events.
24 The other relevant evidence was that of Sese Tuiniua, who was a friend of the appellant. He was interviewed by Constable Martin on 22 May 2002 and an ERISP of that interview was obtained. An edited version of this ERISP was marked for identification 4 at the trial and a transcript of that edited ERISP was tendered in the appellant's case. The transcript referred to a conversation between the appellant and Mr Tuiniua which took place late on the evening of 27 March 2002.
25 Included in the transcript was the following:
"A. Yep, yep, I go to Meli, what are you doin'? What are you doin', mate. He goes, nothin' man, nothin'. Like, like he sounded like shattered, you know, like he sounded like upset for some reason. …
A. Like he had, like he was almost crying you know, he was, he was just about to cry, yeah, like that upset, yeah. …
A. I asked him, I asked Meli, what's wrong? And he said goes, and he said, and he said that, he, one of the boys just shot a copper. And, I said to him, who, who? And he goes, fuckin' Penisini shot, shot, shot a fuckin' copper. And I go, what happened, what happened? And he said that they, he said, well they copped a chase, they ended up losing it. He got out and, and they all started bolting and Penisini turned around and fired shots at the copper. And Meli looked around and seen Penisini shooting at the, at the coppers and the copper, I think. Yeah, and then I asked him if he was all right. He said, he didn't say much, he said, yeah, yeah. And then after that I go, I asked him if he wanted to come up and get drugs from Redfern to, you know, to ease him. And he goes, no, and he, he just walked off upset."
