When Bethany Austin learned that her fiance had been unfaithful in late May 2016, she ended the seven-year relationship and called off their upcoming wedding.

He told the couple’s friends that Austin was “crazy.” To set the record straight, Austin sent their families a four-page letter that contained text messages between her ex and his mistress and nude photos of the woman.

Austin was promptly charged with a felony for violating Illinois’s revenge porn law, known as “nonconsensual dissemination of private sexual images.” In return, she argued that the law was an unconstitutional restriction of her freedom of speech.
