From the Toronto Star – Delhi man faces child-porn charges:
A man spotted by police driving naked from the waist down with a laptop computer on the passenger seat is facing numerous child pornography charges. On Wednesday at 5 a.m., Toronto police found a driver going the wrong way on a one-way street in a residential area. On the screen of the laptop computer was an image of a young girl performing a sex act on an older man. The laptop had a wireless adapter card (known as a WI-FI card) allowing the accused to access the Internet through any insecure wireless Internet signal (known as War Driving).
One more reason to set encryption in your wi-fi network as high as you possibly can.
