Probably because he is in a huge unoccupied area. The crowed is nowhere near as close as it looks on TV with the lenses the media uses. Look at an areal view. Other than SS there isn't anyone within 20 yards of him. The shot also came from the tree line, probably at a downward angle. On top of that, he didn't get many shots off before the snipers took him out.
Edit. It looks like there was someone in the crowed who was hit and killed. Pray for her family.
