She posted a picture of two guys and made public allegations about their conduct which resulted in their termination. To me this looks like grounds for a defamation lawsuit. Did they give permission to use the image of them? Did they admit to making these alleged jokes that she took offense to? There's something seriously wrong with this. I could take pictures of any two guys at an event and put it on Twitter and say they were gay bashing or using racial slurs, and they have no opportunity to defend themselves.
This is seriously messed up.
