Mr Hallowes said witnesses who are police have previously lied under oath, and that the jury will hear lies repeated in evidence.
“We say some police in the investigation had engaged in misconduct,” he said.
Sergeant Gary Silk and Senior Constable Rodney Miller.
Prosecutor Ben Ihle, QC, has told the trial that forensics experts believed 11 shots from three guns were fired: seven bullets from two guns had been fired at the officers, while Senior Constable Miller fired four times. Sergeant Silk’s gun was still in his holster and unfired when he was found dead, Mr Ihle said.
In his opening address, Mr Ihle said he expected the evidence to show Mr Roberts shot Sergeant Silk, and Debs shot both officers.
He also said the prosecution would call Debs, whom it expects to say Mr Roberts “was indeed with him on the night that Gary Silk and Rodney Miller were murdered”.
Mr Hallowes labelled the prosecution’s decision to call Debs “an act of desperation”.
Prosecutors argue both men were prepared to use their guns to avoid capture, and are criminally responsible for the officers’ deaths because they assisted each other, and the shots were fired with murderous intent.
The trial has heard that when Senior Constable Miller’s colleagues found him critically injured, he referred to two gunmen. Those references, Mr Ihle said, included the comments “Two, one on foot” and “Get them, I’m f—ed.”
Senior Constable Miller died in hospital hours later.
The registered owner of the Hyundai was Debs’ daughter, Nicole. She was Mr Roberts’ girlfriend at the time.
Mr Ihle told the jury Mr Roberts’ admission to the armed robberies established tendency evidence that showed he was with Debs in Moorabbin.
The trial continues.
