And I agree with your point. My understanding is waivers don't really mean much in the first place.
thats been my understanding too. in fact, as an educator, i've been told that in the huge picture, people can not sign their rights away. so, if someone wants to file suit, they can. it would always be up to the courts to decide how far the suit can go... no matter how many papers one signs promising not to hold anyone liable, they can still try to sue in court...
