Last week, East Tennessee State University (ETSU) freshman Tristan Rettke was arrested by campus police and charged with a felony under Tennessee’s Civil Rights Intimidation statute after confronting peaceful Black Lives Matter protesters in the ETSU free speech area. Rettke’s act — dressing in a gorilla mask and attempting to hand bananas to the protesters in an attempt to “provoke” them — has to have been intended to be offensive. But, as the ACLU of Tennessee’s executive director observes, the First Amendment precludes the criminal charge against Rettke. It likewise would have precluded ETSU from formally disciplining Rettke had he not voluntarily withdrawn from the institution.
