Notable case

On August 15, 2013, Judge Marten held that an abortion opponent's letter to a Wichita doctor stating that someone might place an explosive under her car, absent sufficient contextual evidence indicating an imminent threat, is constitutionally protected speech and not a "true threat" under existing law. Judge Marten noted that the government supplied no evidence that actual violence against Dr. Mila Means was likely or imminent, especially since after receiving the letter the doctor changed plans to provide abortion services in Kansas.
