I’ll be honest. You are making no sense whatsoever. Maybe someone else can explain what you’re trying to prove.
I’m not trying to prove anything, just show the scene from a different perspective.
We were shown the profile of a man with light coloured, receeding hair, wearing a mask, holding a gun in an image captured on video outside the chamber.
We were shown that image with the suggestion that this was the person who shot the woman. He’s the same man photographed inside the chamber, on the right hand side. imo.
In the interval between when you see him on the right in the chamber, holding the gun and a baton, and his appearance at the open door, the lattice and glass were broken.
And a person with a black hand wearing a black and white bracelet, moved forward from inside the chamber and fired.
The fake sequence serves to confuse the identity of the shooter. Myquestion is, who was the man in the foreground shown in the chamber photograph, dressed in black, wearing a black head covering?
It’s not that I am making no sense, you just can’t see the obvious. The white man with ginger receeding hair doesn’t have a black hand nor is he wearing a black and white bracelet.
Reconsidering, you could be right...it’s all about angles.
