Eichenwald writes that Whitacre lied and became delusional in a failed attempt to save himself, making the FBI investigation much more difficult. "The Informant" details Whitacre's bizarre behavior, including Whitacre cracking under pressure, increasing his mania, telling the media that FBI agents tried to force him to destroy tapes (a story that Whitacre later recanted), and attempting suicide. Two doctors later diagnosed Whitacre as suffering from bipolar disorder. Eichenwald concludes that Whitacre's sentence was unjust because of his mental instability at the time.
