Internal CIA e-mails show the former agency head, Porter Goss, approved a decision by one of his top aides to destroy 92 videotapes documenting the brutal interrogation of two detainees. The emails were released in a document by the American Civil Liberties Union, as part of a freedom of information lawsuit. “These documents provide further evidence that senior CIA officials were willing to risk being prosecuted for obstruction of justice in order to avoid being prosecuted for torture”, ACLU lawyer Ben Wizner said.
