Professor Barry O'Sullivan:

There are other examples about geotagging I have come across recently. A parent told me about an incident that occurred when someone was talking to the child online and said "I know where you live. I know you live in the house with the green door. I know what the car looks like outside." They did this by getting the child to send an innocuous image of the ceiling in their bedroom but the image was geotagged by default. With three keystrokes a person can pop it up on a map, onto Google street view and he or she is now looking at the house.

Someone could be in Azerbaijan playing this really nasty game-----
