How would it have been any different if it happened in her car, on a secluded jogging trail, at a gas station, or in her front yard?
Well, I was trying to address the situation that I hadn't been aware she had been intruded upon. If she had been in her car, she could have been "trapped," while in the other situations it might be argued she might have been better able to escape. This might make a difference in a state with "a duty to retreat," which I don't know exists in Vegas or not, plus, if she was grabbed, it perhaps might not have been possible (unless she could get in a good swift kick to the family jewels). The gas station locale might have presented an opportunity for another person in the vicinity to assist her.
However, endless speculation on how locale might affect the incident is a little pointless. What happened is what happened.
I agree an aggressive defense would have been justified.
