Not changing the hats, collars, badges, patches, shoulder items, or ties, give the officer a light, floor-length robe of that same drab color, a bulletproof vest, shiny black shoes, and their appropriate weapons.
For Highway Patrolmen, picture the same robed garb, but change the color scheme to grey and yello, and give them one of those flat-brimmed hats.
For those that think robed policemen are inefficient or fall over, I reccomend that you read TurtleShroom's official NS Feed page.

The robes are specially made to make running easy, and they are lightweight to prevent unnecessary sweating. Since some policemen can get rather large, we don't want any sweating.

EDIT: Thanks to Nicksylvania's sillouette (and thank you Imerita for the explanation), I can now present a full portrait.
