I watched a bit of it, given there is various angles now in the public domain, the analysis can be left to people who have experience with firearms and those with experience of how they behave.
4:3 aspect ratios is still suspect, but - I suspect these videos may have been filmed vertically on mobile, and on desktop, which is typiclly 16:10 , perhaps people have universally cropped those videos to make them easier to edit / bring attention to the content.
Given the various angles and the consistency of the footage, I would rescind some of my doubt about it being generated.
The more information that comes out, the less I believe that Robinson was the shooter. If Candace Owens statement that there is no exit wound in the back of the neck is factually correct, it is certain that some other weapon shot Charlie Kirk, because very few rounds would not pass through the neck. Only very low powered rounds like the .22 short might not. The video of the palm gun showed very little recoil, as if it were comparable to a .22 short. What is obvious is that the FBI's narrative is impossible, and is not what occurred.
