Last Thursday, there was a courtroom drama that outdid any episode of Perry Mason or Matlock, and drew a bigger audience than any trial since the first O.J. Simpson trial. There were seven prosecutors and five defense attorneys. The sole witness, the accused, a woman 67 years of age, was under examination for 11 1/2 hours with one break for lunch and another break for other reasons. Her calm demeanor was broken only twice, once when the character of Admiral Michael Glenn "Mike" Mullen was impugned (she was angry then) and once late in the day when she had a coughing fit. In the rest of the ordeal nobody laid a glove on her, in boxing parlance.
