You're right.
Something burning was definitely thrown at him.
Would that have been a molotov cocktail?
In my book, that cinches the self-defense angle.
It was a Molotov cocktail and Ive been saying this all day but Ive been ignored. Antifa were torching a nearby auto business and when they threatened the kid and he didnt back down, one of them (I saw the video early this morning) threw a Molotov cocktail, which didnt hit him and actually went out once it hit the ground. Gasoline is a liquid, so what burns is the fumes, and they obviously hadn’t made their device correctly.
It was then that he began to run and they pursued him.
