I assumed the point of body cameras was simply for physical evidence after an incident, that cops might "behave" better due to some psychological effect doesn't strike me as important.
Agreed. I thought that any "nudge" factor was secondary to getting reliable reporting at the scene rather than relying upon corruptible testimony by officers after-the-fact. All the problems stated elsewhere in this thread around discretion in deactivating cameras still exist and need to be addressed.
