First, I believe the official story, but for clarification and speculation:
https://youtu.be/Txs6UxnSHl0
>the vest
In this video Charlie is throwing hats out to the crowd before he sits down and you can see from his motions and his body profile that he is NOT wearing a vest (you see his chest from the front as he moves, and his shoulder blades from behind).
>the mic
In this same video, you can see him go for the chair but a guy in a tan t-shirt stops him momentarily, clips a mic on him under his shirt (presumably clipped to his necklace because you can tell from his back as he leans over that he is not wearing a tank-top underneath either), and pats him on the shoulder. Moments later, as Charlie is in the chair, you see him bend forward and the mic is visible. It looks like one of those puff ball mics on a clip, probably to record his own audio vs the mic in his hand being for the stadium audio.
>the black spot
On his shirt collar is puzzling, no explanation for that, but from the vertical video (the gruesome one) you can see it's there before he is hit.
>different angle theory

In the "flash in the window video" that anon posted earlier, ignore the flash and instead watch on the camera guy at the front of the tent (from the perspective of the video). As long as we're counting camera men, it looks like he snaps a photo at the exact moment of the hit and then puts it down in a pretty quick reaction to the sound. I would say it's probably nothing but examine as you like.
>magic ring
It was from a vertical video posted to youtube which might may upscale and/or pixelize certain details, I think that is the case here. If not then its the singular odd detail in an ai video? Everyone there is a plant or fake? Unlikely, and this meme
>>515772313 comes to mind.
>random old guy making himself a spectacle
No idea. Weird.
>random guy cheering usa
No idea. Weird.
>why only 4 phone vids
no idea. Weird.
Finally, God bless poor Charlie.
