This is a dead topic I think, so not sure this will post, but I'll try to answer.
About 20 years ago, I was driving home from work (Atlanta). I was still in college and was a co-op student at "big blue". Great job, I worked 7 days a week and actually slept under my desk at times. This one night I was driving home around 2am. I think it was a Thursday, could have been Friday. A cop in Decatur (That's home to Emory) pulls me over in front of the courthouse for a having a broken headlight. Fair enough, I was a poor college student, but I'll take the ticket. Not good enough for him, he was trolling for drunk drivers. He spent a lot of time asking me questions and after shining a flashlight throughout my car asked me if he could search my trunk. I told him "no sir, I don't think that has anything to do with a broken headlight". The next words from him were "get out of the car, boy". It went downhill from there. It was a very abusive next 30 minutes...he was careful to tell me it was only him and me out there, no witnesses, until he finally searched my trunk anyway (which he could do now that I was arrested)...in the end, the judge sent me home knowing full well what happened and didn't so much as admonish the police.
Since this happened to me, I've been careful to notice the stories of others. There are some great police officers throughout America; they deserve our respect. Unfortunately, the "brotherhood" protects the bad ones as well.
