It happened to me.  Pulled over for a rolling stop, officer, acting like he hit pay dirt,  forgot about the $6o ticket and gave  $150 - 3 pt ticket instead for no registration slip on hand,  later at court house the Crown Attorney guy makes a big deal about bringing it back down to a $60 ticket but couldn't really answer why that little green slip of paper was worth that much.  The computer in the patrol car tells them who owns the car and if you can price you are the owner?
