Call the cops and keep recording; fukk intervening in a situation like that because the way she stuck about with that gun out, took them punches without trying to move away got me thinking that this is a domestic dispute between a couple and she'll more than likely cry and tell the cops you White Knight'd without her permission and look to get you knocked.
DUDE IS A HOE FOR THEM PUNCHES, BUT THIS TYPICALLY DOESNT HAPPEN TO NORMAL PEOPLE. SHE SHOULDA BEEN RAN OFF WHEN SHE SEEN THAT GUN.
