3We all put our faith in the criminal justice system. We trust the professionals: the police, the lawyers, the judges, the expert witnesses. But what happens when the process lets us down and the wrong person ends up in jail? Henry Keogh spent almost twenty years locked away for a murder that never even happened. Khalid Baker was imprisoned for the death of a man his best friend has openly admitted to causing. And the exposure of 'Lawyer X' Nicola Gobbo's double-dealing could lead to some of Australia's most notorious convictions being overturned. Forensic scientist Xanth Mallett is used to dealing with the darker side of humanity. Now she's turning her skills and insight to miscarriages of justice and cases of Australians who have been wrongfully convicted. Exposing false confessions, polices biases, misplaced evidence and dodgy science, Reasonable Doubt is an expert's account of the murky underbelly of our justice system - and the way it affects us all.
