This is a no-brainer. The professor was clearly way out of line, and the police officer was doing his job. It is as simple as that.
Put yourself in the same situation: You have locked yourself out of your house, and you and another person are trying to break into the front door. A neighbor sees this and calls 911 to report a suspected burglery in progress. After you have entered your home, the police arrive. Would you not be a bit embarrassed to have caused a stir, and be only ready and willing to apologize and quickly answer questions in order to straighten out the problem? Wouldn’t you be thankful that your house and interests are being protected from intruders?
Now, put yourself in the shoes of the police officer, who is well trained to handle these situations.
He arrives on the scene, where supposedly two men have broken into the house, and are still inside, and that there is a good chance that foul play is going on inside. The police enter the house and confront the person inside, who they find is unruly, confrontational, abusive, and uncooperative, –and most importantly, hindering the police from doing their job.
Now, what are the police to think? Who is this man? Will he pull a gun? Where is the other man? Is the other man still in the process of escaping from the house, or is he lurking somewhere in the corners? Is the first man stalling and buying time, by his uncooperation and wild rantings? How are the police to correctly size up this situation? Must they be shot first?
Due to this professor’s wild rantings, false accusations, disrespect, reluctance to cooperate, and hinderance to the investigation, –without rational cause or reason, –than; this was indeed due cause for his arrest. It has nothing to do with race. –dc
