Well, when you say it's ok to run him over, in which scenario? After he kicks her car or after he gets off his bike and starts to come towards her? Baca use unfortunately we don't get the camera angle on what he was doing when he got off his bike.
1)verbal argument
2)biker kicks car
3)driver hits biker with car knocking him over
4)biker walks towards car but we don't know what he does. We do know he ends up on the hood of the car and going for the ride of his life.
5)driver drives into curb, other cars with biker on hood
6)biker reaches in car to get keys so driver can't flee seen
Seems each step compounded a minor altercation and escalated it into a bad situation all around. Where does one draw the line and try and put responsibility? Proportionally? Severely? Surely the use of a car as a weapon should be treated more severely than the kicking of the car. That caused the reaction of the biker to come towards her. BUT, now that the biker has come towards her, you have to get inside her head and she may be fearing for her life. She needs to get out of there NOW! A reasonable response? Who's to say?
Good stuff
