In the movie One Tough Cop, Bo Dietl was being questioned by 2 FBI agents about Dietl's involvement with gangsters when one of the agents mentioned that Dietl could be like Sammy the Bull Gravano, the man that ratted out John Gotti. However, this is impossible because Dietl retired as a cop in March of 1985 and the John Gotti case happened in 1995, 10 years after Dietl retired. This is one huge slip up.
