Defence lawyer, Shaun Ginsbourg, said while Rapson had crossed the line by plying the children with cigarettes and alcohol, it did not make him a sex abuser.

A jury has convicted former Salesian College vice-principal David Rapson over the rape and abuse of eight students.
Rapson, 60, was member of the Salesians of Don Bosco religious order, which operated the Salesian College "Rupertswood", a boarding school in Sunbury, north-west of Melbourne.
Soon after, he was appointed by Pope John Paul II the Archpriest of the Basilica di Santa Maria Maggiore in Rome, where he resides today.
Shanley's accuser, s then-27-year-old firefighter, said the now defrocked priest began abusing him when he was six years old.
The jury was told on one occasion, a 12-year-old boy was given a glass of lemonade that made him feel sleepy. In another case, a 16-year-old boy was given three-quarters of a bottle of scotch before he was indecently assaulted by Rapson.
One of the former students alleged he was raped by Rapson on four separate occasions in 1990.
