I'd say police aren't civilians because they're not acting in their own right; they're a specific designated extension of the state.

It probably depends on your state and your police force though. Gendarmes are military trained IIRC, also in Italy there are something like 7 different types of police.

You are describing an agent of the state, which is a different concept than what the traditional use of civilian addresses.
