The Police Association says a double killer's conviction today for two cold case murders is vindication of the undercover techniques they used to obtain a confession.
Association president Greg O'Connor's comments follow today's sentencing of Kamal Reddy to life imprisonment for the murders of Pakeeza Yusuf and her 3-year-old daughter Juwairiyah 'Jojo' Kalim, after police used an undercover technique known as the 'Mr Big' technique to elicit a confession from him
"The fact that the bodies of two homicide victims were recovered and their killer was convicted is vindication of the innovative and legal method used by police to obtain a confession from the offender," Mr O'Connor said.
"The police's job is to put the best possible evidence before the court to ensure they are able to make the right decision, and the use of innovative and legal techniques achieves that.
"The public should not be swayed by the arguments of defence lawyers who endeavour to prevent this evidence from being heard in court, as the admission of such evidence virtually guarantees the conviction of their client."
Mr O'Connor said the Police Association believed details of how police obtained such confessions should not be made public, so as to ensure the technique could be used in the future and criminals did not become aware of the full details of the technique.
"The family of the two victims can now have double closure -- firstly that they have retrieved the bodies of their loved ones, and secondly that the offender has been brought to justice," Mr O'Connor said.
