In 2005, CIA lawyers reviewed copies of videotapes made during interrogation of detainees and expressed their concerns to Rizzo. He requested the OLC to issue new statements about the legality of the enhanced interrogation techniques. The "Los Angeles Times" reported that Rizzo was becoming "increasingly anxious in the years after the Sept. 11 attacks that agency employees were being pressured to use methods that might later place them in legal jeopardy." The OLC issued three memos, signed by Steven G. Bradbury, then head of OLC, in May 2005 that stated the techniques did not violate the Convention Against Torture, as ratified by the United States in 1994. Later in 2005, Rizzo traveled with other CIA officials, including Kyle Foggo, to several black sites, to assure CIA employees that their interrogation activities were legal. The CIA destroyed most of the detainee interrogation videotapes in 2005, a decision which dismayed Rizzo because it was done without his input.
