Supreme Court to rule on legality of social media threats and stalking.

The Supreme Court is considering whether invasive messages sent to singer-songwriter Coles Whalen constitute a "true threat" in the eyes of the law. The case raises the question of when a threat is a "true threat" and what the prosecution has to prove. The defendant's intent or the effect on a reasonable person? The case involves a man convicted and sentenced to four-and-a-half years in prison for "stalking" Whalen and making "true threats" against her. The First Amendment protects freedom of speech, but there are exceptions, including "true threats."
