Now this is really fair. (NOT!!!) If I were a student at that university on a pre-professional track working my butt off to pull a great GPA and they told me academic slackers were going to get good grades for no effort -- I'd be consulting an attorney to see if I could file suit.
Choosing to cut class to go rioting over someone you don't even know shouldn't exempt you from academic responsibilities.
This is why liberalism is a mental disease. They don't even see that this is unfair to students who apply themselves to get good grades.
