Cops control when the cameras are filming, if footage is retained and what/when/if footage is released. Body cams are just yet another surveillance tool against the population.

I'd suggest browsing body cam footage on youtube for a bit. If you see the sort of stuff being prosecuted it might not bother you.
If it hasn't reduced police use of force or misconduct (I find this claim questionable) I think that's unfortunate but regardless it's important to implement systems that document that to the greatest extent possible. If we do that today then maybe it can be reduced tomorrow.
100% percent of prosecutors’ offices in jurisdictions with body cameras have used officer testimony as evidence to prosecute civilians. Meanwhile I suspect the use of officer testimony is even more lopsided in favor of cops.
And the biggest fix there is you need to not let them control it.
