What follows is a discussion between two typical americans (Tucker Carlson and Patrick Feeney) familiar with shooting all sorts of guns throughout life (starting from childhood) who also are hobby hunters. They are discussing the shot Crooks (by all accounts, so far) was able to shoot considering his gun, the bullets, his sights and the surrounding context. While they are surely not professionals in the sense of a pro sniper, they surely know much more about it from experience than the average citizens of any other country on earth.
Notice that they assume Crooks used iron sights, which, technically speaking, is probably not what happened. Although, if he used a red dot system without optical x magnification, I do think that it is pretty similar to iron sights, just that this version makes aiming much easier compared to iron sights. If Crooks used 4x optical zoom instead (as some suggested is also possible) it makes it quite a bit easier than that:
So it seems, all we can really say is that the first shot Crooks did seems to be very difficult considering the context (even with 4x zoom), because it was able to hit Trumps ear. We don't really know how accurate the following shots were, but it seems like at least the second shot was still very close to the accuracy of the first shot. Which makes it even more astounding IMO. So, we probably have to say that Crooks was able to shoot an almost perfect first shot and possibly a second shot after that. Which seems possible, considering things like luck and skill and such. BUT, right there, we might need to wonder if some kind of "devine intervention" made him and/or the bullet able to do what happened? I mean, what are the chances that Crooks pulled that shot off "all by himself"? Was it just luck and/or skill, or was something "otherworldly" involved? If so, was that otherworldly intervention meant to hit Trumps head? Or, more wildly, meant to only scratch his ear? Or even more wildly, originally meant to hit Trumps head, but then another kind of "divine intervention" kicked in (maybe an STO type?) which caused the "headshot" to become a scratching of the ear instead, by something like causing Trump to turn his head at the right moment and/or causing a wind blowing the bullet slightly off target?
By the way, it now seems to be pretty likely that Crooks encountered that police guy shortly before he shot (and likely pointing his rifle towards him, or at least, starting to attempt that). BUT the time between this and his first shot seems to be short, yes, but quite a bit longer than we assumed previously. It looks like quite a number of seconds passed between the encounter with the police guy and the first shot. Which seems to be a reasonable time for doing so IMO. BUT still, that makes Crooks first shot impressively accurate IMO.
