Ed Vulliamy, who filed the first eyewitness dispatches about Serb-run prison camps in Bosnia, writes in The Observer that journalists should testify at war crimes trials. “I believe there are times in history–as any good Swiss banker will tell you–[when] neutrality is not neutral but complicit in the crime,” Vulliamy argues. “We are entering a new world that seeks not only to report the legacy of tyrants and mass murderers, but to call them to account. Why should journalists of all people–whose information will be of such value–perch loftily above the due process of law?” I tend to side with Vulliamy, but shades of grey are involved, so no journalist should be compelled to testify, or feel compelled to do so.
