Free speech on social media under court spotlight

The US Supreme Court is weighing the free speech rights of people who use violent or threatening language on Facebook and other social media.

The justices are hearing arguments in the case of a man who was sentenced to nearly four years in prison for posting graphically violent rap lyrics on Facebook about killing his estranged wife, shooting up a kindergarten class and attacking an FBI agent.

Anthony Elonis of Bethlehem, Pennsylvania, says he was just venting his anger over a broken marriage and never meant to threaten anyone.
