There is another video. There is a video taken from the same location as the one you linked to, but from an angle slightly farther back, and to the right of this video. In that other vid, a man is seen running out of the parking station, and standing in the roadway where the barricades are, looking at the explosion moments after it happened. In fact, I believe the video with the man in it is the one Q posted, if I'm not mistaken.
