Owing to his time as a POW, McCain was recognized for his sensitivity to the detention and interrogation of detainees in the War on Terror. An opponent of the Bush administration's use of torture and detention without trial at Guantánamo Bay, saying: "some of these guys are terrible, terrible killers and the worst kind of scum of humanity. But, one, they deserve to have some adjudication of their cases... even Adolf Eichmann got a trial". In October 2005, McCain introduced the McCain Detainee Amendment to the Defense Appropriations bill for 2005, and the Senate voted 90–9 to support the amendment. It prohibits inhumane treatment of prisoners, including prisoners at Guantánamo, by confining military interrogations to the techniques in the U.S. Army Field Manual on Interrogation. Although Bush had threatened to veto the bill if McCain's amendment was included, the President announced in December 2005 that he accepted McCain's terms and would "make it clear to the world that this government does not torture and that we adhere to the international convention of torture, whether it be here at home or abroad". This stance, among others, led to McCain being named by "Time" magazine in 2006 as one of America's 10 Best Senators. McCain voted in February 2008 against a bill containing a ban on waterboarding, which provision was later narrowly passed and vetoed by Bush. However, the bill in question contained other provisions to which McCain objected, and his spokesman stated: "This wasn't a vote on waterboarding. This was a vote on applying the standards of the field manual to CIA personnel."
