Then they should briefly go off duty... I fail to see an issue here.

Try not to assault anyone in the stalls?

OK, the above is slightly tongue in cheek, I know, but this seems like a fairly weak "what if". We're primarily talking about confrontational incidents of conflict where there's issues of trust around accounts of events. The majority of these incidents will hopefully not take place during toilet breaks.

They should have to request it over the radio and the camera should be remotely disabled. This would mean they couldn't turn it off in mere seconds in the heat of the moment or right after taking a call before it was resolved. It's not a perfect solution but it's pretty good.

Another option would be for the "off" button to mark that section of the tape as "off duty" and store it in a special archive that required a court order to access. That way the only time we would need to look is if there was some issue where there was an empty spot in the recording during an event where they were clearly not "off duty".

I think it's worth pointing out that while using the bathroom I don't think a chest/shoulder mounted body cam would see much, if anything, inappropriate. It's not attached to their head looking where they look.

More like if your laptop stops working you are obligated to call tech support immediately.

Well, I can’t shoot people to death and potentially get away with it at my job. If I was interviewing for a job where I literally held the power of life or death for other people, then yeah, I would probably expect some pretty strict controls on that power.

If your DLP mysteriously turns off and then corporate data gets leaked you could be brought up on criminal charges that could include jail time. Which is the present scenario nearly all of us are in.
