It's also more complicated for cops than just "not wanting to be monitored all the time." There are interactions with innocent people, children, sex crimes victims, witnesses who need identity protection for their physical safety, etc. where they also need to turn off their cameras. There is definitely some funky stuff happening in a lot of places, but acting like it's a cut and dry issue of "watching the cops" or "not watching the cops," is underestimating the legal complexity here.
