If you think that it is OK for college professors to critique public officials without fear of harassment or retribution, you should hear this story from the Mercer County Voice.
In Mercer County, New Jersey a political science professor, Michael Glass, was discussing the state’s $2 billion shortfall with his students. In particular, he mentioned problems with public employees who “double dip” by receiving full pension benefits while also receiving their full salary following a ritualistic “retirement.” Students asked for an example, so the professor mentioned the elected county sheriff, Kevin Larkin, who had been featured in the local paper for receiving an $85,000 annual pension in addition to his $129,634 regular salary.
A student in the class texted a message that reached Larkin, describing the class discussion. Larkin then showed up at the class later that evening and called the professor out to the hallway. Following their exchange, the professor apologized to the class for making disparaging remarks about Larkin with the sheriff standing right next to him.
Following the apology Larkin left the classroom, saying “This isn’t over.” An aide to Larkin, who was standing in the hall, said as the door was closing, “”You’re a terrible teacher, you should get your facts from a book.”
This story would be completely unbelievable if it didn’t ring so true.

I too hope this isn’t over. I hope they fire the guy and save themselves $200k.
It would probably cost $200K to fire him.
Be glad he’s not a teacher – then it would cost $500K!
