The "Able Danger" Story May Be a Massive Limited Hangout
but still it seems the Pentagon was worried about it:
...the Pentagon bought and destroyed 10,000 copies of a book, "Operation Dark Heart," written by Lt. Col. Tony Shaffer, a Bronze Star recipient and career Army intelligence officer, that contained a chapter on a pre-9/11 intelligence operation, Able Danger.FREEDOM!!!!!!!!!!!!
In a statement, the Pentagon said it "decided to purchase copies of the first printing because they contained information which could cause damage to national security." The books were destroyed on Sept. 20.
