I agree the person crossed the line. It wasn't me who called the police, I don't even have any idea where you are out there in the world. I do agree someone had good intentions but went to far. They should have sent you a message instead.
Some people are extremely good with the internet. My husband had a friend who had his xbox live account hacked. They were then also able to follow his IP address and started hacking into everything else they could find connected to him, and figured out where he lived. They would sent police and pizza men to his house. It was pretty scary to learn how capable people are with hacking.
