The 1994 bombing of the Adelaide National Crime Authority sent shockwaves across Australia. It was a brutal act that killed a police officer and seriously injured others, sparking one of the most daring undercover operations in our history.

But this police sting had an unusual weapon - forensics.

With red phosphorus linking the bombs and a drug manufacturing business run by a key suspect, and forensic experts involved in the operation, this was a rare moment where science went on the offensive.

In this episode, host Liz Porter is joined by Colin McLaren, the cop who infiltrated the Australian Mafia, lived a double life, and brought down a group of organised crime kingpins from the inside.
