For devil's advocate, there's a lot of negative feelings toward workplace surveillance, and for good reason. Having everything you're doing recorded isn't a very good feeling. It really takes away freedoms of judgement and latitude.
Whether or not you think police should have any freedom of latitude is a debate in and of itself, I suppose. I come from a city that has an apparently unusually strong track record with traditionally disadvantaged peoples (POC, homeless, immigrants, etc.) so I have very different gut reactions about police than most of the internet.
