IDK, I feel like if they're filming it, they're not likely going to make a first move.This is an interesting case because the attacker is unarmed but threatening violence and escalating. IMO its more like she was trying to egg them into making the first move so she could claim the victim. The dilemma here is how does anyone know the true intentions under such stress? What could we learn from this ?
If someone is harassing you, then says they are going to beat you that seems to escalate the fear of being attacked as immanent. But does it justify using (or threatening to use) deadly force?
