You are partially right. However, he did show his ID eventually. The cops started to leave but at this time a crowd had gathered. He followed the cops outside and then started his rant about how a black men were treated in the US, he was trying to stir up trouble with the 7 or 8 people who were present and he wouldn't shut up and let the cops leave. He was then arrested. They acted correctly. It is all in the police report. The guy acted like a jerk from the git go, as you stated he at first refused to show ID and screamed at the cops. Bozo is full of sh** on this one and is showing his hatred for whitey.
Gates behaved poorly. Apparently he lost or forgot his keys and had to jimmy (break) the door to get inside. No problem, it’s not his house. The house belongs to Harvard and Gates just has to call Harvard maintenance to fix the door he just broke.
No wonder tuition is so high at Harvard. They hire these vulgarians, provide them with expensive housing, and give them an audience of adoring young students. (and the parents pay $50,000 a year for the experience)
