examples of websites using Schema.org for a given schema, e.g. PoliceStation

Hi,

I am trying to use Schema.org to represent various physical assets in New
York City, e,g, police precinct, fire stations, schools, public
libraries, parks and playgrounds, etc.
Because of the richness of Schema.org, there are often more than one way of
doing things.
I would like to look at concrete examples.

For a given schema, e.g. PoliceStation, is there a way of finding websites
that are using it? Is there a magic query for that?
From a search engine point of view (I used to work for Google), this is
totally trivial to do, as they have this information as part of their crawl.

Having such a list would help convince the skeptics this is totally doable.
It would also spread best practices.

regards,
