2. A software developer for the Nevada Gaming Control Board rigged slot machines
In the early '90s, Ron Harris, a software developer, was appointed by the Nevada Gaming Control Board to code an anti-cheat program. But alongside the anti-cheat program, he secretly designed a hidden switch that triggered a jackpot when coins are put in the slot machines in a certain way. He stole from 30 slot machines together with his friends. He was later caught and sentenced for seven years.
