When somebody says it is time to move on, it means there is something deeply embarrassing that they don't want to discuss in public. U.S. President Barack Obama said that about the Senate Intelligence Committee's report, published on Tuesday, about the Central Intelligence Agency's use of torture in the years after 9/11.

He put the best face on it after Sen. Dianne Feinstein's committee released the 528-page report anyway, talking about how "part of what sets us (Americans) apart is that when we do something wrong, we acknowledge it."

But as recently as last week, U.S. Secretary of State John Kerry urged Feinstein not to release the report now on the grounds that the "timing" was wrong. When would it be right, then?
