Who, This, Policeman, Aiming, At?

Matichon has some screenshots of the first part of the video.



BP: There is a police officer aiming a gun, but at what? He doesn't shoot. There is some noise in the distance, but oddly the video doesn't show any protesters. A fellow officer comes and seems to tell him to retreat/put the gun away which he does. It seems he has spotted the person using the video camera, but then they walk past another photographer. Are there any other pictures/video of the event?

Actually, this blown up still image from The Manager shows his view ahead of him much more clearly. Can anyone see anything?
