I think there are legitimate use cases -- the main one that comes to mind is replacing the police helicopter "eye in the sky" with a fleet of drones. Cheaper, less personnel involved, and far less intrusive for everyone around it. I'm guessing that will be one of the uses, but they're also likely adopt from military tactics (don't cops love pretending they're soldiers?) and use drones as overwatch at "active scenes". In my experience, flying a drone in urban environments is a complicated endeavour. Launching them off rooftops makes a lot of sense as it removes a lot of the LOS obstacles, but you have to stay high -- they won't be peeking into windows or chasing you down alleyways. Manhattan (and any area with tall buildings / skyscrapers) would be a no-go zone. It will be interesting to see how quickly these get lost or stolen, or knocked out of the sky with basic countermeasures.
