I'll try this once again since I was asked.The police are responding to an unsubstantiated report of a break in by two, count them two black males. They arrive on scene and see a front door that has, even according to the Professor been forced and the lock broken such tha tthe professor is calling for a repair. The Cop, still alone now has substantiation of the initial report. maybe he does have burglers, you know, criminals with maybe burgler tools like pry bars, screw drivers, scree and glass cutters, or weapons, the tools of the trade so to speak. The cop looks in and sees a man with a story. The cop wants to identify the man. For officer safety he wants the man to step outside where if he is a burgler he will be undable to maybe grab a gun, knife, or pry bar he had secreted around the home as the officer approached. This is within the officer's training and within the law to issue this lawful order. Remember too that there is another man loose that the oficer is concerned with. The house may be a trap where he can get killed. The Professor gives him lip. He gets loud, belligerent, and is uncooperative. He failed to obey a lawful order. This is a crime in many jurisdictions, though I do not know about Mass. He is loud, offensive, disruptive and is delaying identifying persons and even locating the second person, a very dangerous act.If this happened in Colorado he absolutely would have beeen charged and I would suggest had he fought the charge he would have lost had I been his prosecutor, though before i prosecuted this i would have tried to dismiss the matter after a teachable moment.Now, was this necessary. I do not think so. The officer has discretion and not every misdemeanor has to be charged. Even had it been charged would I have wanted the officer to take the gentleman into custody, no. Again there the officer has discretion. There is an expression we sometimes use. It is contempt of cop. A few officers choose, when they sense contempt of cop, to not exercise their discretion to reflect the best traditions of their departments which are, of course, to protect and to serve. As a prosecutor I never liked these officers as they make everyone's job more difficult. Yes the Professor got heated and was a jackass, and technically he committed a crime, but it was not much of a crime. Good policing here, good explanations, restraint of emotions could have resolved the matter without charges or ugliness. The Professor had a world view and an agenda. He was also an old man and a tired traveler dealing with a frustrating situation. Sometimes you have to let folks blow of a little steam. The officer could have stepped back for his safety, kept eyes on, waited for backup, let the ,man blow a little, and then have reengaged. I would grade the officers efforts here a B up until the arrest and because of that a C. This was not A level work by any means.
