Look My late father in law was the meanest most sadistic cop in that county years ago. He got his jollies beating people including a well know escapee in the early 1960's. Any retired county or state cops about 70 or older could vouch for what I'm saying. He ran the Knox County Penal Farm back in the late 50's early 60's. Yep he also once worked for UT, KCSD, and THP.
That said I have a relative who is a retired UTPD Captain long before things got out of hand. I also knew the former UTPD Chief. He's been retired over a decade is my guess.
I've met good cops and bad ones. I've had an uncle often enough be on the receiving end of a night stick.
That said some of the parties at UT as of late have gotten out of hand and if your a local you know what I'm talking about. It sounds like the parties got moved off campus.
Almost all the cops I know are good cops but there are a couple of bad apples I know. The fact that most cops are still good is why I hate to see these bad apples—the garden sometimes needs to be weeded.
