I take it none of you guys and gals have lived in the southeast.
In the south, cops don't have very much to do. They do whatever they have to to meet their quota, even if it resorts to planting drugs on suspects. I lived in Alabama and also in Tennessee(mostly 'bama though) for nineteen years, and the cops are most definitely crooked. I had some trouble in a small town in Tennessee that was about 20 minutes away from Cookeville a couple years ago, and they fucked with me the most out of any police officers I've ever met in my life.
