I ran into similar problems looking for apporpriate figures for my generic asian police force. decided on using some Chinese regulars from the Boxer period for the time being. So far, I'm using the force as a deterrent to reduce competing groups from sniping at each other in the beginning of a multi-episode pulp adventure set in a port (the police are nearby and will repond to any gunfire, hauling away any suspects cuasing them to miss or be at a disadvantage for the next game). Just trying to keep enough figures alive to make it to the next game.
