referring to my previous post 176, I made a screen-to-screen analysis of the video from @realDJStew724. If you download this video from some kind of provider online or with the program Televzr, you can then load it in Microsoft Clipchamp. This lets you reduce the speed to 0.1 and then double clicking on play button you get screen by screen visualization. You can also crop and zoom and the 5 frames back button is extremely helpful when you miss something and want to go back. If you just look 5 seconds before and 10 seconds after the shooting frame by frame, you can see many dynamic actions coming from windows 2 and windows 3. Below are my findings, but I am sure if you look more closer you will find more.
Window 3: dynamic activity seconds before and seconds after shooting
1: Just before the hourse rides by you can clearly see some rope hanging down, there seems to have a wooden panel or card board right against the window making it possible to reflect. Looking at the reflection you can see a dark red color which comes from the oposite barn where the snipers are.
2: Rope position changes, Window is cracked open and the snipers are visible on the roof
3: Rope position changes again, first it looks like an oval, but rather it is somebody pulling up the string giving a half oval, the other half oval could be the reflection of the roof of the barn.
4: Rope is gone, panel is gone, no more reflection, the room is dark…
5: head lamp on
6: Keep in mind all above 5 immages are taken before the shooting, shotly after the shooting very active light moving around in this window, maybe somebody is looking for empty shell casings? There is an animated GIF file that shows how much the light is swarlling around in that room.
Window 2: dynamic activity seconds before and seconds after shooting
1 – 3 head lights spotted in the dark
4: after the shooting somebody looks out the window
As you can see, we can all say with great confidence that there were people in building 6 during the shooting The fact that they are in the dark with headlamps on seems suspicious to me.
