The questions from the civilian spokesman at Fort Lewis started sounding suspicious to Sarah Olson. He had called to ask the Oakland freelance journalist about the accuracy of quotes in her story about Lt. Ehren Watada, which had appeared on the liberal Web site Truthout.org. As the telephone conversation progressed, Olson realized that the military was using her to fortify its case against Watada, whom it was prosecuting as the first commissioned officer to refuse deployment to Iraq. While Watada faces a court-martial next month for conduct unbecoming an officer, the U.S. military pursues Olson. Last month, military prosecutors subpoenaed the 31-year-old writer and radio journalist, asking her to appear at his court-martial, scheduled to begin next month, to verify what Watada said. If Olson doesn't testify, she faces six months in jail or a $500 fine and a felony charge for a story she was paid $300 to write. Olson doesn't want to be part of a legal action that she believes limits someone's free speech. She came to journalism six years ago ... hoping to create more places for dissenting or seldom-heard voices, not fewer. Journalists should not be asked to participate in the prosecution of political speech," Olson said. [She] isn't being asked to reveal unpublished work. "What I don't understand is why they (prosecutors) can't get this information digitally," said Fidell, president of the National Institute of Military Justice. Olson doesn't have a problem with journalists testifying in court. She doesn't want journalists to be coerced to testify in cases that could limit free speech.
