3) Ron Harris – Coding machines for own profit

In an instance of a protector-turned-perpetrator in the 1990s, Ron Harris, who was in charge of writing anti-cheating software for the Nevada Gaming Control Board, coded machines for his own profit. He rigged the machines to pay huge amounts of money by installing software. He reportedly rigged 30 slot machines and sent in his accomplices to insert coins in certain sequences, who walked away with thousands of dollars. Harris was sentenced to seven years in prison in 1996.
