The female motorcyclist is an acquaintance of mine. (23. 5-foot-3. 110lbs soaking wet. She's a "real" rider. Not a poseur.)
I'd been hoping it wasn't her, but just got confirmation it was.
Dude had her on the ground and was trying to break her neck by twisting her helmet around, and she managed to get to her gun... and stop him.
She has been released with no charges. Self defense.
