They should have never been deployed to begin with.

How expensive are drones? Way less expensive than a police officer. They can be deployed at scale. You can imagine a world where every move everyone makes is tracked. If you don't think public spaces hold any 4th amendment protections, they can also see much better into private property that police officers can't see from the street. Back yard, second story windows, all angles into windows, and that is only considering if they use regular cameras, imagine when they have thermal cameras or other sensors.

I can't help but wonder what skin color those young men had that made the police suspicious in the first place...

They didn't do anything to even be "evaluated", but you already knew that...

my opinion: we need a lot more context here. It is dystopian to have advanced and arguably “stealth in an urban environment” drones conducting surveillance for benign activities. What was the suspicion? Matching the skin colour of an APB, or something more?

I’m sure most people have no problems with drones being used for hot pursuit, appending those charged with murder, etc; but this is highly advanced technology that deserves more scruinty and accountability.
