New witness or charlie kirk shooting says Tyler not the shooter

Witness statement:

"Watching the video of the impact, hearing the sharp crack instead of a big hunting rifle's boom, and seeing what looked like a shorter rifle platform, albeit with the absence of the shape of a standard 30 round magazine (the assassin may have used a 10 or 20 round magazine only expecting to shoot once or twice), I would guess that he was shot with a hornady V-max or similar lightweight, .223 bullet designed for very rapid expansion. Of course I don't have access to any autopsy reports like you might, but if they found small shards of copper rather than one larger copper-coated lead slug, that's the gun and bullet I would expect was used."
