Like all freedoms free speech has limits, responsibilities and, as any lawyer knows, the possibility of consequences.  I can freely speak a lie about someone but should expect to get sued.  I can freely insult an entire population of people but should expect to pay a price.
Public figures in this society forego privacy and are held to a higher standard of behavior.  A high-profile educator in a profession many people hold in low esteem as one devoid of conscience has more practical limits on free speech than an obscure person like myself.  Is this the way it should be?  In a society ruled by logic, fact and reason the answer would be "No".  But people are emotional creatures and often hypocritical so as a public figure Professor Shurtz should know and expect that her action has consequences whether laws or policies were violated or not.
