Abraham Gilbert Saffron was a successful Sydney businessman who hated his nickname and spent a fortune trying to have it expunged from the record by threatening anyone who used it publicly.

The name was Mr Sin and it was well deserved. He built a vice empire on a triangular business model – the three points were bribery, blackmail and arson.

He organised sex, often with under-age boys and girls, secretly photographing patrons to use against them. 

He paid bribes to police - $750 per club for local police and $5000 a week for senior police and was so brazen he repeatedly visited the bent Deputy Commissioner Bill Allen at headquarters.

Six of Saffron’s many properties caught fire between 1980 and 1982 - all deliberately lit. 

On June 9, 1979, the ghost train at Sydney’s Luna Park was engulfed in flames, killing six children and the father of one of them. It was a property Saffron wanted to own.

The police investigation was a disgrace, not because of incompetence but corruption.

Saffron said he wasn’t involved but he would, wouldn’t he?

Robbo' Robertson was a natural undercover cop. A Vietnam veteran with the gift of the gab, he slipped seamlessly into the role of Brian Wilson, an underworld heavy from Sydney.

In 1978 Robertson was given a new mission. He was to go deep undercover to infiltrate Australia’s best armed robbery crew, the men behind the 1976 multi-million Great Bookie Robbery.

He was to pretend to be a corrupt armoured van driver who would tip the team about a lucrative payroll. But this time police would be waiting to make the arrest.

What they didn’t know at the time was that one of the gang was the notorious NSW prison escapee Russell “Mad Dog” Cox.

In the final meeting before the armed robbery Cox and Robbo were stopped by three uniformed police, unaware of the sting operation.

Cox pulled a gun and only the quick thinking and quick talking Robbo saved them all.

In 2021 Robbo finally received a Valour Award for his heroism.

It was a Friday night when Federal Police contacted their Victorian counterparts with an urgent message. A shooting had been ordered by an overseas bikie boss to be carried at a Melbourne fight night.

The planning was so detailed police moved in to seize two stolen cars to be used by the hit team, cloned plates, and guns. Someone is walking around today unaware they are alive because cops unscrambled the encrypted message.

What the arresting officers didn’t know is the original tip didn’t come from an informer but something much more reliable.

As part of an international police sting over three years police had monitored 27 million encrypted messages from crooks from 300 cartels using a purpose-built app called ANoM.

The app had been built with a trap door for police and spread through the world enabling police to monitor criminals in Australia, US, Europe, Asia and South America,  

In the end police made more than 1000 arrests with more than 200 in Australia alone.

In 1984 policeman Ron Fenton was nearly given up for dead. Shot in the head and slumped unconscious next to his police car. That is until a cop in an unmarked car took it upon himself to charge do drag Ron to safety. They thought Ron wouldn’t make it to hospital, then that he would not regain consciousness and finally that
he would never return to work. They didn’t know Ron. He battled back and eventually was back on the road. But it came at a cost – he would suffer PTSD and leave the Force to battle his demons alone. Depression, flash backs, mood swings and vicious night terrors had led him to attempt to take his own life. That is, until he met Yogi, a companion dog trained by an inmate in Bathurst prison. The dog and the prisoner saved Ron’s life.

He was the best defence lawyer representing murder defendants in around 200 cases. He went on to be a respected Supreme Court Judge presiding over the most difficult homicide trials, including the Walsh Street police killings, the Russell Street bombing that killed police constable Angela Taylor; the Bega double murder trial of Leslie Camilleri, one of two men who tortured and killed NSW schoolgirls Lauren Margaret Barry, and Nichole Emma Collins in Victoria in 1997; and the trial of serial killer Paul Charles Denyer, who killed three women and stalked hundreds in the Frankston area.

He has represented Mick Gatto and Mark 'Chopper' Reid among other Melbourne gangland characters, but even as a school-kid, lawyer Bernie Balmer had an aversion to bullies.  As a year 11 student he had a difference of opinion with a Brother at Assumption College who responded by punching the young Balmer in the face. Bernie, who would go on to be a more than handy heavyweight boxer, dropped the bully.

While he was only defending himself, he was forced to leave under threat of expulsion. It still burns that some who knew the truth failed to stand up for him and perhaps that is one of the reasons he became a seven-day-a-week defence lawyer, often giving a voice to those who desperately need one.

Balmer is respected on both sides of the law and has a unique insight into the criminal justice system.

Graeme Alford was a smart, cunning, hard-working criminal lawyer with a loyal and regular client base all connected to the feared Painters and Dockers Union. It was a licence to print money.

He was also a heavy punter and prodigious drinker - both vices that are not unknown in the legal fraternity. Eventually, facing huge gambling debts, he stole from his trust fund, was jailed and became a full time criminal.

It was October 15, 1982, when a half-drunk Alford donned a balaclava, grabbed his shotgun and with fellow armed robbers burst into the Chapel Street Prahran branch of the National Bank. He was a better lawyer than bandit and was arrested at the scene.

We speak to the police who nabbed him and to Graeme about his descent into the underworld and his battle to reclaim his life.

Wayne Sherwell was a country cop on traffic duty on a quiet rural road when he pulled up a speeding motorist who claimed to be a vet. The man behind the wheel was calm and matter-of-fact and there was nothing initially to make the cop suspicious.  

In fact he was the notorious 'Country Bandit' who made a specialty in robbing regional banks. The confrontation ended with the bandit dead and the policeman recognised as a hero. But for many years Sherwell had to live with the ghost of the man he killed.
