I think it would generally be a good thing for cops kicking down doors to have working body cameras; the state's monopoly on violence is easily abused, and should be carefully monitored.
But if the cops get the wrong address for their no-knock warrant, kick down my door, and find me jerking off in my bedroom - I would prefer the footage not be made public.
They the controls do exist, just not at the capacity required to do it for literally every single hour of footage recorded by body cameras. Hence why they do respond to requests for specific incidents but not blanket or bulk requests.
If they had to do this for all footage then the police department would likely respond by decreasing field officer counts to reduce footage, as well as shift resources away from law enforcement activities and towards redacting the massive volume of footage.
Are you saying that a child in the car with their DUI parent deserves to be on a YouTube bodycam channel because cops have to appear uncensored in the same video? I genuinely don't understand how you could mean anything else, and that makes me think I misunderstood. I sure hope I did.
If these controls don't exist inside the organization, they shouldn't exist for the public either.
