OK, so we have two guys who are shooting the first shot? That is a problem…
I was one of the first guys that mounted the animation of Crooks on the roof complaining the lack of dynamics not seeing him moving and no recoil. See my post from August 9th:
Please compare my animation (which was mounted to a gif at that time) with yours. As you can see manipulation has been applied in the meantime to his shoulder to add more dynamics to this video, because nobody believed the first version because of lack of recoil.
And another thing: Crooks, or shall we call him “Goldielocks” in this picture got himself a sexy hair wave, or was the person tying to apply more dynamics to his shoulder simply careless?
If this video has been edited, we can’t take it seriously as proof. We would be needing the original one from the cell phone directly, that would be more convincing.
My hypothesis is that Crooks waited or was not ready and the first 3 shots were fired by the 2nd shooter then Crooks nervously shot 4 – 8 into the crowd with rapid speed shots not really aiming, because Trump was already on the ground, killing one person.
