Some special operations service members and veterans are unhappy that retired Navy SEAL Robert O'Neill has taken credit publicly for killing Osama bin Laden.

Earlier this week, O'Neill acknowledged that he had fired two rounds into the forehead of the al-Qaida leader during the 2011 raid on his secret compound in Pakistan.

O'Neill says more and more people were becoming aware of his role and that his name was bound to become public anyway.
