Reggie Buddle, 60, Puyallup, Washington, sentenced July 30, 2007, for Unlawful Wearing of United States Military Medals and Decorations. Buddle posed as a decorated Marine Corps Chaplain presiding over weddings, funerals and baptisms. Buddle was sentenced to 500 hours of community service and two years of probation.
