When you look at how alarmingly close BG was to Libby's position on the bridge, combined with the odd angle in the second frame, it seems to me like she may have just swept across him with her phone/camera... in the act of putting it away... in order to move away from him.wondering why LE has not released even like a two or three seconds long clip of the video showing BG walking across the bridge.. wouldn't that be more useful and offer a more clear picture? it could be more helpful.
I really think these may be the only 2 images there are of him from the video.
