A Michigan man is being prosecuted for using a cafe’s free WiFi… from his car. Sam Peterson was arrested under a Michigan law barring access to anyone else’s network without authorization, according to Michigan TV station WOOD. Since the cafe’s WiFi network was reserved for customers, and Peterson never came into the cafe, he was essentially piggybacking off of the open network without authorization.

Coincidentally, the cafe owner that Peterson was leeching WiFi off of didn’t even realize that what Peterson was doing was a crime at the time. Neither did the police officer. “I had a feeling a law was being broken, but I didn’t know exactly what,” Sparta police chief Andrew Milanowski told the TV station.

John has written about this “problem” in his PC Magazine column:

The person who owns the signal has to be the responsible party. Grabbing a nearby signal because it is being beamed into your house or car is hardly the same as going into an unlocked residence and stealing the silverware. And it’s not hacking if the signal is not protected. In fact, if I’m getting unprotected signals on my property from people nearby, they’re the ones who are trespassing! What if I do not want these signals interfering with what I want to do?

The way I see it, if someone is shoving a signal down my throat like that, I have every right to use it any way I want to as long, as I’m not doing anything illegal. It’s crazy to think that my using that intrusive signal is illegal.
