Brian Coghlan is laid back, an asset he was able to use in his workplace. As a prison officer, he quickly learnt that being seen as a good guy around bad people was the key to life behind bars.For 26 years at Port Phillip Prison, he dealt with the worst society had to offer – sex offenders, serial killers and manipulative mass murderers who knew they were destined to die in jail.He spent most of those years working in the top-level protection unit that housed the likes of Peter Dupas, Julian Knight, Raymond "Mr Stinky" Edmunds and the Bega schoolgirl killers.Coghlan decided very early to deal with each inmate on the basis of how they behaved in jail, not what they did to get there.In this episode, he talks to John Silvester about the tricks to surviving in jail, as an inmate and as a prison officer, and his unique insight into some of the country’s worst inmates.
