The one he hit was the first one he was trying to avoid. He came around a blind corner and the shirtless, hooded kid is running at him from the right side of the street. The driver (who does appear to slow down) tries to avoid the dumbass in the hood. When he sees the crowd on the left he straightens out just in time for the dumbass to run into his car. The kid in white you pointed out is clearly heading to the left side, as he should, and isn't in any danger.
Dude, you seem to be the only person here who can't see what went down. Bad show.
And once again, high walls, structure on the right, blind curve, people with hoods charging the car. This is an ambush, plain an simple. My initial reaction would be to instinctively react to a kid in the road, right up until the ambush buzzer started going off in my head, at which point my concern for those kids is fucking nil. I'm a reasonable guy and largely sympathetic towards the Palestinians, and I can assure you that if it were me driving, that kid probably wouldn't have walked away.
