Seems to be fascinated by the end of the barrel. . .'whats that little thing there on the end?'. . .think Kerry was sensing trouble in his body language with his own gun when pict was taken. . .so thought he would just be preoccupied for a moment on the barrel next to him.
I love that shot! It is a priceless photo on par with the algore photo of him with his head over the loaded M-16.
