@Much2learn - I agree that there is more to be done by ALL universities. Policies, procedures, education, etc, should constantly be scrutinized for ways to improve. However, regardless of what is done, this serious issue will (sadly) never be completely eliminated.
As far as what should have been said by the President, I don’t think a graduation ceremony is the place to say it. IMO, graduation is a time for students and their families (many who have traveled thousands of miles) to celebrate the accomplishments of thousands of students over many years time. It should not be a forum for anything other than that (though, I’m not sure Ken Burns got that memo). Perhaps the President should have done or said more, but graduation is not the proper forum.
