Here's a tale out of Michigan about a man who was arrested for using Wi-Fi outside a cafe from his car. Interestingly, the arresting officer, the arrested man and the cafe owner didn't know the man was doing anything wrong until the officer in question decided to do some research and found a law he thought fit:

"He didn't issue a ticket, but he did hit the books. 'I had a feeling a law was being broken,' the chief said, 'but I didn't know exactly what.' He found a relatively new and rarely used law. 'Unauthorized use of computer access,' he said."

Maximum penalty for the felony? Five years in prison and/or a $10,000 fine. The 1979 law the officer finally discovered was apparently updated in 2000 to help prevent skulldruggery via Wi-Fi.

There was a similar story out of Alaska back in February where a man had his laptop confiscated for using free library Wi-Fi after hours to play World of Warcraft.
