Details about the daring raid by U.S. Navy SEALS that killed Osama bin Laden have always been top secret.
Now, an upcoming new book, No Easy Day: The Firsthand Account of the Mission That Killed Osama Bin Laden is raising a firestorm of controversy.
The book's author is "Mark Owen," the pseudonym for a former member of SEAL Team Six commando who the publisher said, "Was one of the first men through the door on the third floor of the terrorist leader's hideout and was present at his death."
The book is being released next month, on the anniversary of September 11. The true identity of the SEAL has been shrouded in secrecy, until now. He's just been identified by FoxNews.com as Matt Bissonnette and was reportedly one of the SEAL Team Six leaders of the Bin Laden mission.
Here's what INSIDE EDITION has learned about Bissonnette: he's 36 years old and he is from Alaska. He retired from the Navy SEALS with the rank of Chief and completed 13 combat missions following the September 11th attacks.
He faces possible legal trouble because The Pentagon said it had no idea he was writing a book.
But, CBS national security correspondent, John Miller wonders if the Navy will really go after one of its own.
Miller asked, "Here you have a true American hero, part of the team that went in on Bin Ladin and took him down. Now, I guess the gamble is, are you really going to come after a guy like that?
INSIDE EDITION's Lisa Guerrero spoke to former Navy SEAL, Don Mann about the controversy.
Guerrero asked, "The fact that this Navy SEAL has now been outed. Could this be dangerous to either him or his family?"
Mann replied, "Yes, he and his family are going to be at risk for the rest of their lives."
This is just the latest controversy surrounding the secrets of the Bin Laden raid.
A new movie, Zero Dark Thirty, was originally scheduled for release in October, but has now been moved to December after Republicans proclaimed it would unfairly dramatize one of President Obama's signature achievements right before the election.
