If the article is accurate, Officer Harris was clearly assaultive in his behavior.  I'm guessing there will be further investigation based on the publicity from the article.  I hope so.  Road rage is a very, very scary thing.  Having officers with "quic tempers" is a very scary thing.  Having an off-duty officer given a "free pass", if indeed that's what happened, is a very, very scary thing.  .....somebody's got some 'splainin to do."  Gary Crum
