Hi Shruti,

Sharing possible ways that I know of to find and build the data you're 
looking for from the generally available map platforms. Sentences in 
brackets give more background info for people new to the subject. Note: I 
am adding an important caveat at the bottom.


*OpenStreetMap or OSM* (the all-open commons alternative to google maps 
that you'll find members of this community earnestly pitching for) way:
Relevant tag/key-value pair : "amenity=police" . Link: 
https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dpolice 
Query on Overpass Turbo (the "backend" of Openstreetmap and the quickest 
way to search download specific data): https://overpass-turbo.eu/s/LX6


*Google Places API* (the more complicated "backend" of Google maps which 
while having more coverage for now, is way more restricted both technically 
and legally and the reason why you'll find members of this community 
earnestly pitching for moving to OSM / enriching OSM instead )
... lists "police" as one of the POI types than can be searched and 
retrieved programmatically.
Link: https://developers.google.com/places/supported_types

Note: Since the term "poiice" is generic, the direct search may also throw 
up places that aren't police stations, eg: police training institutes. It's 
safe to assume any dataset you get will be messy and will need considerable 
manual work on it to get to an acceptable stage. 


*Caveat:* We cannot expect full coverage or any proper answers about extent 
of coverage (The usual answer to "does this cover everything?" is "Nobody 
knows!") because that requires some official institution putting the data 
out there, and if there had been one then one wouldn't need to search on 
general map platforms. So what you get here is typically a perpetual 
work-in-progress cobbling-together of data by ordinary people volunteering 
time and effort. It will probably never be "complete" but it's much better 
than nothing. The remedy to lack of coverage is to start contributing to 
the common well and get others to do the same.
