No Easy Day hits bookstore shelves

The much anticipated memoir of a Navy Seal who helped kill Osama bin Laden hit bookstores Tuesday.

Presales already made the book number one on Amazon's best sellter list.

But the Pentagon may not be as eager to see the release of No Easy Day: The First Hand Account of the Mission that Killed Osama bin Laden.

Last week, the Pentagon general counsel threatened legal action against the former Navy Seal who wrote the revealing book.
