People need to go back and re-learn logic. These two are NOT the same.

Teachers are being asked to record their lessons to the students. This is literally what they're paid to do. The quality of their work is measured by listening to their lectures and watching their class room management. Further, if a child misses class for illness or whatever, a recording would allow them to keep up remotely. We don't record their conversations with fellow faculty in the teacher's lounge or in staff meetings with the principal. We don't record their time during planning periods, nor when they're grading papers or when they're relieving themselves in the toilet. Those things have an element of privacy.

Congressmen are paid to make laws. The parallel here is to record their speeches on the floor of the Congress, their motions, their votes, etc. And we do this meticulously. Congressmen listen to stake holders from many angles on any of their issues. Anything that affects a business is going to prompt someone to try and go persuade the guy not to make laws that screw over his business. We don't record the Congressman while he's in the elevator catching a 30-second pitch from a student activist. Why? Because it's not official business, and you should be entitled to some time to yourself to think and plan or to have confidential conversations that are sometimes necessary in any profession.

I'm not saying this because I think lobbying is fine as is. The base concept is how representative government should work. People should interact with their Congress critters to push their interests. Every time you fire off an angry email to your representative or call your senator's office, you're lobbying. The issue is the financial rewards and quid pro quos, and that needs a different solution than body cams.
