In a social network connected world, it seems auto theft will be a thing of the past. A car dealer had a relatively rare Nissan Skyline GT-R stolen recently and posted this information with pictures on the internet. The next day someone spotted the car, snapped a picture of the thief and in short order followed him to his house where the thief backed in with his license plate exposed.
The directions to his house were subsequently posted online with a map and directions.
Needless to say, he was arrested and the video of him being taken away is online as well. Gotta love the Internet.
