That witness is not very credible, because the police report declares that there was a full moon, page 9 of 25 per "
Investigation", and there is a very bright street light on the location, and there is near a full half mile of flat level road which the cop was driving down, and the police vehicle did have fully functioning headlights too.
So the visibility was NOT "poor" as is claimed, and since the lighting and visibility was clear then the color of Mr Baird's clothing becomes irrelevant, because it was the cops job of driving to look ahead and to avoid any accident.
