Have you checked to see if the Police have an Omnibudsman or something like that? You could file a complaint with them perhaps?

As for the uniform, they may not have a choice in regards to that. I know the cops here in Toronto where dark blue uniforms (although they can wear shorts sometimes). I've never seen them with reflectors or vests (other than bullet proof ones) and imagine they get fairly hot under all that gear and such. But perhaps you can suggest the idea of leg band reflectors (those that go around the ankle) as something the force should consider in the future.
