"No Easy Day," written with journalist co-author Kevin Maurer, takes readers inside bin Laden's compound in Abbottabad, Pakistan on the night of the May 2011 raid. At times, Owen's account differs from the "official" version given by the White House, especially when it comes to the moment of bin Laden's death.
White House spokesperson Jay Carney told reporters days after the operation that though bin Laden was unarmed, he had "resisted" before he was shot. By Owen's account, another SEAL shot the terror leader as his head was poking out a doorway, apparently before he could have made any moves to resist.
Little said blocking the book's release today was not really an option available to the Pentagon given how copies had already gotten out into the public domain. He also said no effort will be made to block its sale at military installations .
"It is not our typical practice to get into the business of deciding what and what does not go on bookshelves in military exchanges. But that doesn't mean in any way, shape or form that we don't have serious concerns about the fact that this process of pre-publication review was not followed," he said.
Maurer said that after spending months with Owen writing the book, he was convinced Owen did not write the book out of vanity, but to "share a story about the incredible men and women defending America all over the world."
Dutton, the book's publisher, said in the book's announcement that a majority of the proceeds will go to the families of fallen SEALs.
