I don't know if the rest of the article is behind a paywall, but I don't see anything about a policy.
The only policies I've heard of are either police department policies -- which is just codified laziness and refusal to do their job -- or district attorney policy which, as I said, shouldn't be relevant to whether or not police make arrests. It's their job to arrest people for crimes, not to solely arrest people for crimes for which they think they can get a conviction.
