Canadian diplomat manual: prisoners in USA at risk of torture

I saw this article (U.S. in Canadian manual as possible torture site) on cnn.com. Part of me wonders why this is considered newsworthy. Isn't the U.S.A. the only country that doesn't admit (since the current administration, at least) waterboarding is torture? Actually, that might not be true. I have no idea whether countries like Israel, Afghanistan, China, Egypt, Iran, Saudi Arabia, Mexico and Syria admit to torturing prisoners (and in the above article Israel denies doing so).

Anywhoo, main points of the article:

• Training manual for Canadian diplomats: U.S a place where prisoners may be at risk
• Israel, China, Iran, Saudi Arabia also are on list; Canada says it's not official policy
• Manual cites U.S. interrogation techniques and singles out Guantanamo Bay, Cuba
• Document inadvertently released to Amnesty International lawyers working on lawsuit
