The Washington Post's Robert Barnes has a preview of arguments next week in the U.S. Supreme Court in the case of United States v. Elonis. Anthony Elonis made several threats on Facebook in rap-style lyrics toward his estranged wife, law enforcement, schoolchildren and co-workers, and he was convicted in federal court of making "true threats" toward most of those people. At issue in the Supreme Court is whether the test for proving someone guilty beyond a reasonable doubt of making a true threat should be whether they subjectively intended to make good on the threat or if a reasonable person would view the speech as a threat. At issue are " the unique qualities of social media," Barnes writes. "In this rapidly evolving realm of communication, only the occasional emoticon may signal whether a writer is engaging in satire or black humor, exercising poetic license, or delivering the kind of grim warnings that have presaged school shootings and other acts of mass violence."
