If this were after the bomb exploded and killed him, where's the blood all over his white shirt and white pants? Where's the blood, guts, and body parts all over the street and car? Where's the damage to the car? Ah, this was a clean bomb as opposed to all those dirty bombs.
Why do the man's clothes look normal and he has his legs casually crossed?
If he was already laying there like this when the bomb went off, shouldn't his shirt be destroyed and covered with massive blood and guts?
Why is there no blood or splatter surrounding the victim on the car or pavement?
Why are the guys wearing bomb suits if the bomb has already detonated and killed him?
