Indeed this whole assassination does not pass the smell test from the info available so far as it is reminiscent of the attempted assassination of President Trump in Butler. No surprise if some element of the deep state was behind it but hired/found an amateur lunatic to do the murder like Crooks. Notice much of the surrounding evidence in that case disappeared to this day.
Going out on a limb here, and I assume it will be chopped off, but consider he may not be the shooter, but a decoy.
