Police Car hits Pedestrian in Wheelchair- charges against pedestrian dropped

Please watch this video of the incident involving the police vehicle:



You can read more about this case and another involving a truck and wheelchair pedestrian HERE. From the article:

"... the case of Gerry Mitchell, who was struck by an Albemarle County Police cruiser on November 5 and then ticketed. His charges were dropped on January 6, and Mitchell has not announced whether he’ll pursue a civil case against Albemarle County Police or Charlottesville Police who ticketed him hours after he was struck."

I thought the rule was that pedestrians had the right of way - I suppose there is an "unless" in there somewhere.
