One example where I think this would clearly be great - if the police were able to respond to most crimes (eg gunshot, robbery, car theft) fast enough to establish line of sight with a drone, and then follow at a safe enough distance - so no cops firing at perps and hitting bystanders, and no police chases causing collateral damage. Drone first responders might be cheap enough and fast enough to get extremely low response times across the city. I think there are lots of reasonable objections to pervasive surveillance (I don’t want widespread drone patrols), but very rapid response times seem like a way to get many of the benefits with few of the downsides. (Just don’t weaponize them, please…)
