This is an incredible piece of video. At the 1:20 mark you clearly see some greenish figure moving through the crowd.
Between the crowds of protesters and barricades, the video shows a flowing, pale green image that resembles an erect rider atop a horse in Medieval-like barding.
The ethereal figure remains for a few moments before floating over protesters' heads and off the screen.
Is this the Fourth Horseman of the Apocalypse?"
Kinda spooky, any ways.......
