He still had her purse right? I'd say she has the right to retrieve her stolen property using whatever level of force she deems necessary to be effective and minimizes her capacity to come to harm. You can't just tell people they have to sit there and watch a crime being committed against them. It could be their livelihood being taken away from them. They have the right to retrieve their property, even if that force could be potentially deadly. If you don't like it, don't steal.
But once property is retrieved it should be required to deescalate the situation and use minimal force. Either just detaining or fleeing. No revenge justification.
How is running him over going to make him give you your stuff back?
