Don't be a victim. Make a plan, take action, and remember that when seconds count the police are just minutes away.
The only thing I didn't see in the story is where the individual armed themselves for protection. But you know, I can't completely fault them for that. Buying a tool you are scared of or don't know how to use doesn't make much sense. But they took notice of their environment, took proactive measures, and involved the authorities.
Not too much to fault in that story.
