OAR doesn't have jurisdiction over what an arrogant jerk does, regardless of his status as an 'Officer of the Court,' when the jerk is not in court or breaking any laws. Should the Real Estate Board, another licensing entity, take up punitive measures when a realtor engages in unprofessional, but not illegal, behavior, ie: honking her horn more than she should at the guy who's taking too long to cross the street? How about the Medical Board fettering out a Dr. for glaring at someone who brought 15 items to the 10-item lane at King Soopers...? 
You people and your need for government intervention at every impropriety, real or perceived, is just astonishing. How would you survive if you didn't have somebody to whine and tattle to every time you don't like someone's behavior?
I guess the, clearly exceedingly difficult, task of going to Harvey's website and matching up the picture of the offending attorney to the bad-actor above - and not ever using his services - is just too much work?!?
