I don't believe they were on their phones with dispatch after the original accident.But if she was so frightened by them, why leave her locked up home and go outside? She knew the police were on their way. She had a loaded weapon.
If they had walked across her front yard and began knocking on her door, I could understand her being frightened. I would have shot them myself if they were pounding at the door, threatening to come inside. Even that would be illegal, but if there were 3 of them and they had followed her home, it might have been considered self defense.
But I cannot believe that she was severely afraid and so she went OUTSIDE to confront them. That doesn't make sense to me at all. That sounds more like anger than fear to me.
Also, those 3 men did follow her home. But they were speaking to the 911 dispatcher at the same time. If they had followed her to do harm to her, they wouldn't be sitting on the phone with dispach, imo.
I firmly believe that they would have been told to stand down and back off.
