They don't have to drive down the street to memorize the locations of ring cams. They already know who has them. Hell, amazon gave them a map (https://www.yahoo.com/entertainment/2019-12-03-amazon-ring-v...). I don't think every police officer is going to take the time to track down every camera over a package thief, but I do agree with the EFF that it'd be very very easy for police to take note of individuals and neighborhoods who habitually refuse to give them video and that any interactions with them could be influenced by a perception that they are "uncooperative" or "unsupportive of the police"
The article you link isn't a primary source, it links back to your previous CNET article, which explicitly says it's a heat map and specific location is not given. Welcome to shitty "tech" journalism playing the telephone game. You start with a pretty tame report, and 2-3 articles down the line, Ring is suddenly giving your new born baby to the government.
Nowhere in the original there's talk of giving user location, yet Yahoo someone starts talking of "detailed map of doorbell installation", for whatever definition of "detailed".
"the heat map showed police where Ring cameras are concentrated: the darker the shade, the more the cameras. But when zoomed in, it would show light circles around individual locations,"
It also links to other cases where maps of cameras were sent to police by amazon such as the one shown here:
