You don’t really believe that all congressional conversations are recorded do you?
Sure the law may require that, but that is not how it actually works.
Not a bit. I doubt that any are (at least legally). AFAIK, no law requires it. My point is that they "should" be.
I am of the same opinion about "public education". Every classroom should have two webcams...one at the front of the room viewing the students, and one at the rear of the room viewing the teachers, blackboards/visual apparatus. The idea that ANYTHING should be taught or said without the ability of parents to see it should be anathema. And if the kiddies knew that mommy and daddy might be watching them in class it would likely cut down on misbehavior.
If you are a "public servant" (officeholder) or public employee, you should HAVE no "privacy" other than for body functions. Your employers (us taxpayers) should be able to tune you in at any time and see what you are up to.
But the technology and laws are evolving in the exact opposite direction, with our nascent overlords (aka "public servants") able to view and access whatever we (taxpayers) might do (drones, GPS tracking, and God knows what else) without those devices/laws applying to themselves.
