In a September 7, 2007, public address to the Council on Foreign Relations in New York, rare for a sitting Director of Central Intelligence, General Michael Hayden praised the program of detaining and interrogating prisoners, and credited it with providing 70 percent of the National Intelligence Estimate on the threat to America released in July. Hayden said the CIA has detained fewer than 100 people at secret facilities abroad since 2002, and even fewer prisoners have been secretly transferred to or from foreign governments. In a 20-minute question-and-answer session with the audience, Hayden disputed assertions that the CIA has used waterboarding, stress positions, hypothermia and dogs to interrogate suspects—all techniques that have been broadly criticized. "That's a pretty good example of taking something to the darkest corner of the room and not reflective of what my agency does" Hayden told one person from a human rights organization.
