As Jason Roberts spends his first full day of freedom in more than two decades, questions are turning to whether he could receive compensation for his time behind bars.
Roberts was acquitted on Monday of the 1998 murders of Victoria Police officers Sergeant Gary Silk and Senior Constable Rodney Miller.
The officers were staking out an armed robbery target in Moorabbin in the early hours of August 16 when they were ambushed and killed by Bandali Debs.
