Do I need to see This?
Oh man, that is horrible.
Easy to see why the death toll was so high. Most people looking the other way. A few looking toward where the truck was coming from. Just three seconds from when truck first spotted (about a 60 yards away) to impact by camera phone. Most probably never new what hit them, or only had a brief glimpse. With the attack lasting about 120 seconds, he averaged a bit less than two hits per second.
Did he hit five people in the three seconds where the truck is traveling in the video? You cannot see it, but it is likely given the crowded conditions shown.
Better lighting than I had imagined.
