tried to protect themselves by fighting back. Escobar's faction, initially both the most powerful and violent, rapidly disintegrated in the face of attacks by the rival Cali Cartel, Colombian police/army, organs of the U.S. government, and vigilante paramilitaries. In 1992, in exchange for Lehder's agreement to testify against Manuel Noriega, his sentence was reduced to a total of 55 years. Three years after that, Lehder wrote a letter to a federal district judge, complaining that the government had reneged on a deal to transfer him to a German prison. The letter was construed as a threat against the judge. Within weeks of sending that letter in the fall of 1995, Lehder was whisked away into the night, according to several protected witnesses at the Mesa Unit in Arizona. According to journalist and author Tamara S. Inscoe-Johnson, who worked on the Lehder defense during the time in question, Lehder was simply transferred to another prison and continued to be held in WITSEC, the U.S. Bureau of Prisons' version of the federal Witness Protection Program. Inscoe-Johnson argued that Lehder had not been released, despite Internet rumors to the contrary. Inscoe-Johnson also believed Lehder would never be released: allegedly, he would be privy to secret information regarding the CIA's and his own involvement in the Iran-Contra affair. On July 22, 2005, he appeared in the U.S. Court of Appeals for the 11th Circuit to contest his sentence. Lehder appeared pro se, arguing that the United States failed to carry out its obligations under a cooperation agreement he had entered into with the United States Attorney's Office, after he held up his end of the deal. (United States v. Lehder-Rivas, 136 Fed. Appx. 324; 2005). In May 2007, Lehder requested the Supreme Court of Colombia and the Colombian government to intervene in order to comply with the extradition agreement established between Colombia and the US, which stated that a maximum sentence of 30 years would be applied to any extradited Colombian citizen. Lehder argued that, having already served 20 years in prison, which corresponded to two-thirds of the 30-year maximum time stated in the treaty, he had completed his legal sentence and should therefore be released. In May 2008, Lehder's lawyer declared to El Tiempo that a habeas corpus petition had been filed, alleging that Lehder's cooperation agreement had been violated and that "a court in Washington" had less than 30 days to respond
