The cops actions are vetted and have responsible party attached. The camera is used to bypass responsibility of bad actors entirely. Infact the camera is used to enable bad actors instead of catching bad actors. Huge difference in my opinion but okay just shrug your shoulders and claim there’s no difference.

And, crucially, cops are expensive, so the percentage of drivers they can do this to is low.

Whereas a stationary camera can scan the license plates of ~100% of cars that go past it and save that data for later fishing expeditions. And is cheap enough that we can (and have) blanketed roads with them.
