I watched that several times last week, and I wasn't convinced that he was the shooter. The bald-headed guy was very close to the line of fire, and there were too many people who should have noticed white-shirt guy doing that. I think he's just doing something spasmodic with his hands. A gun or something like it (cell phone gun) should be visible, and it's jut not.

The scenario on this vid fits the entrance/exit wounds much better. IMHO.

Regardless, and as usual, the official narrative is shit, and that kid they've framed didn't do anything at all or was in on it.
