Police body cameras and the swing of the pendulum

Not too long ago, there were people that were demanding all police body cameras, all the time. I have previously noted some flaws in that model, most recently here.

Now people have apparently discovered that body cameras expose more than police brutality - and the previous "cameras always on" mantra is being modified just a bit. Examples:

For example recent legislation in some states strictly regulates when police should turn the cameras off. In the District of Columbia, officers are not allowed to record at a school if they are engaged in “noncritical contact.”

Connecticut prohibits officers from recording in a hospital, mental health or other medical facility unless they are engaged in recording a crime suspect.
