The ability to turn the cam off while you shit could easily have come with a rule that states that if you turn your cam off while doing cop stuff you’re fired, but it didnt.

Easy. If you turn off your cam, you’re not a cop anymore, you lose your legal powers.

Take a shit while turning off your cam? No problem, you don’t need to be a cop for that.

Shoot someone after “accidentally” turning your cam off? You just killed someone likely while trespassing with no qualified immunity. Enjoy prison.
