Thankfully, the Overpass API supports an around operator. One needs to be careful with queries that return many nodes, and the query likely to return the fewest nodes should be first. Bounding boxes help.

Here's an example for the second query:

<query type="node">
  <has-kv k="amenity" v="brothel"/>
  <bbox-query {{bbox}}/>
</query>
<query type="node">
  <around radius="1000"/>
  <has-kv k="amenity" v="police"/>
</query>

<print/>

You can see it live for Berlin:
