Also keep in mind that while it’s happening, you have no idea how far this individual intends to go. Were they just intending minor theft? Or maybe they broke into your car because they were trying to get to you? If they announce their intentions, do you even believe them?
Of course it’s easy to make the decision in the middle of the day with perfect information. Now picture waking up at 2am to sounds in your drive way and there’s 2 or 3 guys out there fucking with your car.
