Here's my take...
The store manager was an idiot for jumping up on the hood of the car! No doubt about that!
However, just because of her gross lack of judgment, she was still an innocent victim who could have been killed or crippled for life, if the car ran over her if she fell off the hood.
I have ran more then one idiot who got run over after riding on a car hood just for fun and getting run over after falling off. Let alone being on the hood of a car driven by a criminal trying to escape the scene of a crime. (One of the joy riders I ran was killed and two were critically injured.)
The ccw holder didn't shoot her before issuing a challenge... He pointed the gun at her and commanded her to STOP! It was at that point where she smiled at him and swerved directly towards him.
His broken foot and the fact he was on crutches, I believe should go a long way to support his contention that he was forced to shoot at that point. (Clearly a "disparity of force" situation, with a car vs. disabled citizen)
Having limited mobility, could reasonably be argued that he couldn't, with certainty be able to move out of the way of the woman trying to run him down.
This opinion is merely based on what is reported so far. Without further details, I reserve the right to change my opinion on this incident.
