how is a police station area a commercial area?

If you encounter mistakes like that, it is best to add a public changeset discussion comment (to https://www.openstreetmap.org/changeset/91723649 in this case) and ask the mapper to reconsider.

Ignoring tagging for renderer:

1. amenity=police was tagged on the building, instead of the compound
2. landuse=commercial is "misinterpreted" as any office and non-industrial service activity.

It's true there are no widespread-enough landuse= tag for similar complexes hosting multiple POI-s/functions with common properties (although not a problem here), when you look at =institutional, =police (cf =military), =prison, =civic, etc.
