A class of fourth graders got an education on the justice system when they sat through the court calendar of District Court Judge Douglas Herndon. They then got to test their chops in a court of law with a mock trial: The Ministry of Magic vs. Harry Potter. The students from the Meadows School were prepped by their teacher for their day in court. They played the roles of judges, jury, attorneys and witnesses. The fabulous fourth graders peppered Judge Herndon with questions; he in turn, grilled them about what they learned. They appeared to have learned a lot. Two more mock trials are scheduled with Judge Herndon April 18 and May 4 at 10 a.m. in courtroom 16D at the Regional Justice Center.
