The Colorado Supreme Court is considering whether a teenager's tweets are considered free speech. The case stems from tweets sent between two students, in different states that did not know each other, that included threats of violence in the aftermath of the shooting that happened at Arapahoe High School in 2013. One of the students was arrested for harassment, but his conviction was overturned. Traditionally, for something to qualify as a true threat, there is usually a face-to-face confrontation where the harm would potentially be imminent. Experts now say they believe the courts might eventually need to decide whether a person's fear of harm is enough to constitute a true threat.
