[2] He has analysed some of Australia's most prolific and violent criminals, including underworld figure Alphonse Gangitano and mass murderer Julian Knight.
[8] Three notable individuals Watson-Munro has worked with included Julian Knight, Alphonse Gangitano, and Mr Cruel.
"Mr Cruel" is a pseudonym for the never-identified suspect of several child rapes and the murder of Karmein Chan in Melbourne during the late 1980s and early 1990s.
[9] Watson-Munro was the psychologist responsible for assessing and working with Julian Knight after he carried out the 1987 Hoddle Street massacre, killing seven people and leaving 19 injured.
[5] Watson-Munro was assigned to treat deceased Melbourne underworld figure Alphonse Gangitano shortly after his arrest for allegedly murdering petty criminal Gregory Workman.
[10] Gangitano was released after the prosecution dropped all charges relating to the arrest after a key witness left the country.
He noted truancy and crime being committed by children in the care of the state and called for a royal commission into the government department responsible.
He considers such proposals well intentioned, but that real issues of youth suicide in Australia need addressing, such as socio-economic circumstances.
[17] Watson-Munro has stated that individuals who consume true crime media and are socially isolated, mentally ill, or young can become desensitised to violence and gore.
