EDS NOTE: OBSCENITY - This photo provided by the American Civil Liberties Union, which was presented as evidence to the U.S. Supreme Court, shows a screenshot of a Snapchat post by Brandi Levy, left, in which Levy and her classmate raise their middle fingers as they pose in a convenience store in Mahonoy City, Pa., above a profanity-laced message written by Levy. The posting has ended up before the Supreme Court in the most significant case on student speech in more than 50 years. At issue in arguments to be heard Wednesday, April 28, 2021, via telephone, is whether public schools can discipline students over something they say off-campus.
