Fitz didn't get terminated due to "sexual abuse". No one even claimed such things. Some of the pontificators threw nebulous terms like "sexualized" into their press bubbles - because they know which terms trigger the masses. But, even at that, such terms were for public fodder - that certainly wasn't what "triggered" his dismissal.
Fitz didn't get fired due to "hazing" either.
It's a clown show of the highest order. The two newbies to Northwestern - Schill and Gragg - really have done a number. I've never been a worshipper of Fitz, and he certainly doesn't need my help or support, but I would hope he pursues legal recourse and ends up with 2-3 times the $50 million or so they owe him.
Schill and Gragg (and, presumably, the Trustees at NW) won't have to pay for it out of their own pockets (too bad about that), but at least it would serve as some partial retribution for Fitz.
