I still think it sucks. I think people should be able to say what ever they want without some body saying I will tape what you say and then give it to people who want to control what you say. There was an quote by a guy who said I don't aggree with what you say but I will defend the right to say it. I believe that. If the professor says a lie then call him on it.
If a professor says something in a classroom, he or she should be able to defend it both from a factual viewpoint and from the viewpoint of it's applicability to the subject being taught. That's their job! Especially if this is being done at a public university where the professors are being paid in part from tax money.
Anything that a professor says to students should be able to stand the light of day. There should be no secrets in the classroom. I as a taxpayer have every right to know what's going on in public university classrooms.
