After so many people analysing the video, I conclude there is a good chance that it was pre-recorded, edited and then streamed on Facebook as "livestream" - does anyone know if Facebook could show non-live videos as live? . But there could likely be real victims, which might not all be the same as in the video. Some of the victims could have participated in a police/military (which took place at the same day coinkidently?!!!!!!) drill before the real shooting, which at a later part in the same drill could have gone to real shooting (by whom and how many is the question). Can anyone cross-reference people in the video with any of the 50 dead people?
