Apples and oranges - that Harvard professor wasn't killed by that cop. He rightfully had due process even though he was being an asshole to that cop. I remember thinking at the time when the story broke wondering why he just didn't go to his mail box and grab a piece of mail and showed his ID to the cop to prove that it was his house. There is no law anywhere that I know of that says you can't break into your own house unless maybe there is a restraining order against you and you can't be there.
It was definitely escalated further than it should have been but hey, I'll never have a beer at the Whitehouse so maybe it was worth it for both parties. I'd happily break into my house and get arrested if I could go have a beer with the POTUS and the arresting officer. It sounds like a fun day after just being in cuffs and in jail for only a few hours. LOL
