I think the disconnect is that in DISCO Section 31 is presented as a legitimate agency. It could have become one after ENT, and isn't by DS9, so I'm ok with the explanation of it's legitimacy being removed after the Control fiasco, which is why it's even more underground and nebulous 120 years later.
Yeah, having laughably lax security measures isn't exactly new to this episode. But as others have mentioned above, Sickbay seems like the most likely place not to be heavily monitored.This is Star Trek. Cameras are needs of the plot. Most "mystery" episodes would be over by act one, if they had cameras where they should.![]()
