It's been a while since I last saw the Men on the Sixth Floor video but I do remember that Factor said they hid the guns in false bottom wood crates. Wes
Yeah, so why didn't Oswald do the same?
And they would still be visible to everyone as they ran down the stairs and out of the building.
They would be visible to Jack Dougherty, stood a few feet away from the stairs on the 5th floor immediately after the shots.
They would be visible to Dorothy Garner on the 4th floor, and to all the women who were looking out of the windows in that area.
They would be visible to Eddie Piper and Troy West on the first floor.
They would be visible to Baker and Truly racing towards the back stairs.
Jarman, Norman and Williams would've heard shots coming from different parts of the floor above and heard this group of people running for the exits.
They would have no way of knowing if there were police officers around the back of the building when they exited the back door.
