I only got to hear a portion of the Mike & Mike appearance by Paul Pierce this morning, but it sounds like it went well. Red's Army has a bullet-point review and shares this info about Paul's arrest:
He also talked about the Vegas incident. He joked that he was pulled over by a Lakers fan and was charged with DWC: Driving With Championship. That was the line of the morning. He went on to explain that he was driving home after a boxing match and trip to the casino. He was pulled over for failing to signal a turn… and cuffed because of his intimidating size (which is what the cops told him).
