I was told by my Irish bosses in the NSW Prison system that Moriarty was an Irish cop in Dublin.

They say he went on to write a condensed version of the law which was printed in their contemporaneous notebooks, which were ultimately called their 'Moriarty.' A tradition that exists still with English Police.

Whenever they came upon me on a post in the prison at Long Bay, they would say, "I'll be checking your Moriarty Mr More-E-R-I-T!"

One of the Irish Executive Officers would sing as he continued his patrol:
"OH! he was a Bobby on the stalwart squad on the forces of the DMP and as he walked along you could hear the girls all say How are you going More-E-R-I-T?"
