One of the reasons I will not get involved in a potential deadly situation between strangers.
Just from the video, one can’t tell who was right or wrong. Looked to me like the woman had the guy on the ground, holding him down and punching him. Then fell/tripped and was on top of him. She wouldn’t let go, and even got in some extra punches after the cop came.
The guy was barefoot with a small backpack. Looks like he might have been homeless. He might have started it, or she might have taken offense at him for asking for some spare change.
