I watched the video a couple of times without the audio and concentrated on the victims physique. There is a moment where the victim is standing with their back to the camera and she/he sure looks like a guy from the back, broad shoulders, larger arms, looks like a skinny guy. A another shot shows him/her with their shirt almost pulled up, looks like a guy. Definitely, does not have women hips either.
Of course, that still doesn't justify what these two POS did to her/he
I saw the same as you did. Just means they are in more trouble which is good. They are too violent to be on the streets, IMO.
