In an op-ed piece, Temple journalism professor Christopher Harper criticized New York Times public editor Margaret Sullivan's defense of leaks by government officials. "She has apparently become a supporter of [Pfc. Bradley Manning] who leaked more than 700,000 documents about U.S. involvement in Iraq and Afghanistan," he wrote. "Unfortunately, she runs roughshod over some critical facts. Manning…has pleaded guilty to 10 charges, including the misuse of classified material. He has maintained his innocence on 12 other charges...But if he is innocent, why did he plead guilty?"
