How Google Maps Got Me Out Of A Traffic Ticket

This didnt happen to me, but this person used google maps (and an open wifi connection in court) to get himself out of a traffic ticket.

I wonder how many other people have used a laptop in court and have stolen open wifi access to plead their case?

I gues EV-DO or some other cellular based connection could have been used, but the luck to find open wifi in court is pretty cool.
