A Grand Rapids Community College criminal justice professor, known for his unique teaching style, has resigned after showing a video in class of a man having sex with a pig, according to students and a faculty representative.

A school administrator confirmed that Samuel Naves resigned Feb. 17th, but would not comment on why he left.However, students and a faculty leader said the resignation had to do with the video. They said Naves was teaching an introductory criminal justice class earlier this year when he was going through video files on his computer.The video appeared on a projection screen and students begged Naves to show the 10-second footage, according to the accounts.Faculty association president Fred vanHartesveldt told the Associated Press the incident occurred this year. He said Naves was known for a blunt teaching style.
