Do you want to know a not so fun but interesting fact about that picture? The bullet was still travelling through that NVA guy's head when that photograph was taken, the shutter was trigged at around the nano second the bullet left the barrel of the revolver as the photographer who took it was startled by the sudden gunshot.What does the speech bubble say?
"Oh, I'm sorry I thought you were [Damien? Danzin?] You all look alike to me .... [Mitt? Pity?]"
It's magnificently baffling, tho. Is it supposed to be a reference to that 'Saigon execution' photo?
