In such a situation the police simply "can't win."  First, it's my understanding that this a "drug sales" arrest.  Doe anyone suggest the police should NOT make such an arrest if they observe someone selling (yes, I know allegedly selling) drugs?  Should downtown Eugene (or anywhere else)  be a "free sale zone" where the police simply ignore such activity?  Yes, pot sales at those licensed outlets are legal.  Pot sales (or sale of illegal drugs) in the Park Block is NOT legal.  Secondly, the man in custody was "resisting arrest"....passively, to be sure, but,willful, non-compliant behavior to avoid being placed in the police car doe, I believe,constitute resisting arrest.  

Did the arresting officers handle things well?  IMO, they were physically unable to 'cuff the man and place him in the car.  They spent several "long" minutes trying to do so.  This allowed the crowd to gather and become inceasingly aggressive.....not a good deal.  A "bad show" on everyone's part....
