My Commute home from work via Fort Langley and 96th Ave. I had a 'little' disagreement with a police officer on the way home. I was riding along 204th Street and heard a siren burst. I didn't realize it was a police car at first (no markings on the car) until he then flashed the coloured lights and hit the siren again. He tried to order me to ride on the side of the road through his opened passenger side window while driving beside me. Oddly he did this at a point I was already close to the curb. It was on a residential road with a parking lane where the curb extends to the driving lane narrowing the road in several places. I was riding as I was supposed to be maintaining a predictable path only taking as much of the lane as I needed to do. After I stated I was where I was allowed to be according to the law, he hollered back "I am the law". I answered back to him that he should double check section 183 of the BC motor vehicle act before he tried to suggest that I was breaking the law. He of course didn't issue a ticket or fine as I would have certainly challenged it. It would have been a bit embarrassing for him had he done so.Then he just drove off making a left turn a little farther up the road. It's pretty sad when the people entrusted to enforce the laws are ignorant of them themselves.
