text:  CBS's Scott McFarlane reports on the U.S. Supreme Court ruling against prosecuting a January 6th rioter with a federal obstruction charge. The obstruction of an official proceeding charge wasn't just used by the Department of Justice, it was frequently and quite effectively used by the Department of Justice. They charged nearly a third of all the defendants with this count, with this felony, and they batted a thousand, nearly a thousand, at the trials involving January 6th defendants.
