Another observance. The Doctor keeps pointing to the beeping heart/vital signs monitor.
No patch contacts are on the boy, thus useless as an broken clock.
He later starts applying them but in an emergency situation with presumably major wounds, heart monitoring would be secondary to stopping bleeding / wound care.
Also with wounds that are life threatening one could expect at least some blood splatter. Not horror movie puddles but at least on the gloves, sleeves, etc...
As for the missile, I wound think the type the Israelis use would shred a child, even with an indirect hit.
However an thrown together,homemade rocket assembled with unreliable materials could certainly fall short of it's intended target and kill Palestinians instead of Israelis.
I think the boy is indeed dead but the video was an reenactment for use against Israel.
This is not in any way sarcastic, but just curious why you think the boy is dead and not merely faking it. FReepers have good eyes--just wondering what you saw.
