At Anthony Elonis’ trial for making threatening posts on Facebook, the prosecutor told the jury it didn’t matter what Elonis actually intended, as long as a reasonable person would perceive his statements as a true threat. In reversing Elonis’ convictions last week, the Supreme Court held that in a prosecution for threats proof of the defendant’s intent actually matters a great deal. In Elonis’ case, that ended up spelling the difference between being a convicted felon and just being a jerk.
