yeah that account had a perfect summary of what I've seen going around. I copy it below for others:
"The individual spotted on top of the roof before the shooting (the person who appears to have been the actual shooter) might not have been the actual shooter either. The exceptionally graphic video evidence of the attack might be playing tricks on the eyes; the wound that was visible in the video evidence so far may have in actuality been an exit wound for a shot that came from Kirk's 4 o' clock position. Some video evidence supports this, however much higher quality footage (such as from the professional media equipment recording the rally) will be necessary to determine if that is a viable line of investigative effort.
Again, focusing on details that can help find the killer and eliminate future threats is worth the speculation, especially as the FBI has stated that they recovered the rifle used to conduct the attack from a wooded treeline near the campus. This rifle appears to have sported an optic which was mounted too far too the rear to provide a feasible shooting platform. This detail has caused many to doubt that this rifle was the one used in the shooting (as in, it's yet another decoy), or that the shooter did not have the experience to know that the scope was in the wrong position for it to be used properly. In short: If this rifle was used, the suspect is either of a very small body type (much smaller than the suspects sought so far), or they are now sporting a facial wound caused by the recoil of the firearm driving the scope into their face. Or, this rifle was not used at all, and whomever staged it did not have the forethought to position the scope correctly.
As with most high-profile events like this, some discrepancy among the initial details is very much expected. However, there is a LOT of debate right now regarding whether or not the murder of Charlie Kirk was a professional assassination. Right now, all of the evidence in the public eye suggests that Kirk could have been killed in a more coordinated manner (as in more than one person might have been involved), but also by someone displaying very amateur tradecraft. On the other hand, if the multiple misdirections were deliberately planted to confuse and slow down investigative efforts, this would be a strong indicator of more organized planning.
Sometimes the most likely explanation is the simplest, and based on the sheer number of people celebrating his murder the chances of this being one of the usual suspects is rather high, even though the door must remain open to other possibilities. The cold hard truth right now is that regardless of how Kirk was killed, he was killed for a reason. And right now there are millions of people celebrating his murder, both online and in the real world. It is this important observation that will have lasting impact for some time, both in terms of societal shift, but also in terms of real-world threats and security concerns."
