There is some dispute over who fired the fatal shots, but most accounts are that O'Neill shot bin Laden in the head at some point. According to a deeply reported article in The Intercept, O'Neill "canoed" the head of bin Laden, delivering a series of shots that split open his forehead into a V shape.
O'Neill's book says the operators had to press bin Laden's head back together to take identifying photos. But that wasn't the end of the mutilation of bin Laden's body, according to Jack Murphy of SOFREP, a special-operations news website.
Two sources told Murphy in 2016 that several SEALs took turns dumping round after round into bin Laden's body, which ended up having more than 100 bullet holes in it.
Murphy, a former Army Ranger, called it "beyond excessive."
"The picture itself would likely cause an international scandal, and investigations would be conducted which could uncover other operations, activities which many will do anything to keep buried," he wrote.
