It’s possible he was released because he is rich and/or a football star, but…. The initial reason for the stop was speeding. If he simply rolled down his window and left it down he would have never been detained at all. Once the tempers settled down, he might have been released even if he wasn’t a football star.
Cops should not be subjected to being blinded to whatever is going on inside a car they just pulled over. Requiring the window to be left down is in no way unreasonable.
