WORKING AT KEEPING IT REAL- updated graphic based on new data:

What appears to be a molotov cocktail may be a plastic bag back-lit by the lights giving the appearance of having been lit on fire. In any event Rittenhouse (armed individual) is still in retreat attempting to deescalate after warning the attacker (Rosenbaum) by momentarily standing ground after the object is thrown. Rittenhouse then attempts to flee again with Rosenbaum still in pursuit.

The way I see it……
