By looking at topics as varied as mafia mobility, money laundering, drug networks and gang violence, Dr Sergi sought to identify similarities and differences across the four policing models; both in the strategies used to deal with them and the long standing perceptions various institutions have of them.
Through interviews with policy makers and law enforcement agencies, she found that, despite there being a lot of operational similarities between, for example, the mafia in Italy and the biker groups in Australia, the authorities are used to looking at how they’ve been labelled as opposed to analysing the way they behave.
Dr Sergi also makes the point that mafia type groups and organised crime groups need to be seen in context with the culture from which they originate, for example mafias are a product of both the southern Italian culture and the Italian legal culture.
