“I was a homicide detective.”
“It was a masterclass in how not to run an investigation.”
“Identification evidence, as you know, as all detectives and lawyers know, is notoriously unreliable.”
“The media is stunned to hear that the person who's alleged to have done this is Harry Blackburn, the former superintendent who was in charge of scientific.”
“The only changes I, I'd like is this right to silence.”
“The DNA matches that of the eighteen-year-old Somali bloke, Farah Jamma.”
“What happens in court is that, you know, the prosecution says DNA is essentially infallible.”
“It is eight hundred, this is, this is the actual figure that was used, eight hundred billion times more likely to have come from the young man than anyone else”
“DNA is not infallible. Well, that, that. Without, without corroboration, there was no other corroboration.”
“They go with the evidence and they obviously, the only evidence, DNA, they go, well, can't be wrong.”
Veteran journalist and author Neil Mercer returns to I Catch Killers for part two of his confronting examination of wrongful convictions in the Australian justice system. In this episode, Neil and Gary Jubelin revisit one of the most embarrassing periods in NSW Police history: the case of Harry Blackburn, a former police superintendent publicly branded a serial rapist and paraded before the media before he was ever formally charged. They unravel the extraordinary chain of failures that led to his very public downfall, a saga that only ended when a Royal Commission finally exposed the truth. They also unpack DNA evidence, long considered the gold standard in forensic science, and just how far from infallible it can be, and the broader, systemic issues that allow innocent people to be wrongly convicted: unreliable eyewitness identification, the historical use of "police verbals" and false confessions, inadequate legal representation, and the unique challenges faced by First Nations Australians navigating a justice system not built with their language or culture in mind.
