Jose Rodriguez, the former director of the CIA’s National Clandestine Service who landed in controversy over ordering the destruction of videotapes of terrorism suspects being interrogated, is writing a book in which he will explain why for the first time.

Rodriguez is unabashed that enhanced interrogation techniques used on top al Qaeda operatives produced information that ultimately led to Osama bin Laden, who was killed by U.S. forces last weekend.

“The actions we took in the aftermath of 9/11 were harsh but necessary and effective. These steps were fully sanctioned and carefully followed.  The detention and interrogation of top terrorists like Abu Zubaydah, Khalid Sheikh Muhammed and Abu Faraj al-Libbi yielded breakthroughs which have kept this country safe,” Rodriguez said in a press release.

The Justice Department decided last year that no CIA personnel would face criminal charges for the 2005 destruction of hundreds of hours of videotapes of harsh interrogations of terrorism suspects Abu Zubaydah and Abd al-Rahim al-Nashiri. Zubaydah was subjected to waterboarding and it was believed that the tapes included footage of that.

“Hard Measures” is scheduled for release in spring 2012 and is to be co-authored by former CIA spokesman Bill Harlow, who also co-authored former CIA Director George Tenet’s book.
