Your link describes the incident thusly:
"...Crouching in terror behind his father, who struggled in vain to protect his son from the gunfire, Mohammed was shot. He died there, cradled in his father's arms, after both father and son frantically pleaded for help..."
I remember an incident, caught on videotape (or film) that clearly showed a cowardly, clueless man absolutely failing to do what was required to (at least attempt) to protect his son from gunfire.
If it is the same incident, there's been a bit of 'revision' of the facts of the event.
I don't think that's fair.
He had nothing to fear from Israeli forces, they were in no position to hit him or his son. In his mind, he had nothing to fear from his fellow Arabs. If you look at it that way, in truth as it developed, every single one of his movements is understandable.
