Idk, having a bunch of government surveillance drones doesn't really sound great... Maybe we just don't need this level of surveillance at all?

It's absolutely worth looking at the ROI on these flights and weighing that against the intrusion on our privacy/freedom. No doubt they'll always need drones and helicopters but I'd be surprised if there was any real need for them to be in the air that often. I think that's a question that should be asked everywhere but the LAPD in particular are terrible enough that it makes this a great place to start.
