From CNN:

In a statement to CNN, Cunningham said defense officials observed the September 20 destruction of about 9,500 copies of Army Reserve Lt. Col. Anthony Shaffer’s new memoir “Operation Dark Heart.”

In the memoir, Shaffer recalls his time in Afghanistan leading a black-ops team during the Bush administration. The Bronze Star medal recipient told CNN he believes the Bush administraton’s biggest mistake during that time was misunderstanding the culture there.

Not long ago I finished reading Jawbreaker by Gary Berntsen, which was heavily redacted by the CIA. The redactions are so thick in parts that is is almost comical.
