An exposé in Mother Jones magazine chronicles the story of an American named named Naji Mansour who was living in Kenya. After he refused to become an informant, he saw his life, and his family’s life, turned upside down. He was detained, repeatedly interrogated and ultimately forced into exile in Sudan, unable to see his children for years. Mansour began recording his conversations with the FBI. During one call, an agent informs Mansour that he might get "hit by a car."
Disturbing. He did nothing wrong and had his life destroyed, and I am very sure that he's not the only one - but sadly only few people are brave enough to stand up against this.
