Why, wi-fi. Why?

You may have heard about the guy in Florida who was arrested for using someone else's wi-fi network to get to the Internet. Unless there are more facts about the case that aren't being released then I have to say how utterly stupid this is. I'm not 'borrowing' bandwidth from anyone. I don't even have a wireless access point, but I completely disagree with this case. If the guy was cracking into a computer on the wireless network, or he was using this other IP to traffic in kiddy porn or some other illegal activity then sure, lock him up. If all he was doing was using the Internet then I have a hard time calling this digital tresspassing. The 'offender' was on the street and as far as I know he wasn't accessing any of the computers on the network. If you water your lawn and some of the water runs out in the gutter and down the street and I scoop it up to water my lawn, I'm not stealing water. Likewise, if your network extends beyond the boundaries of your property and there is no security, whatsoever, then I say it's fair game. I've heard the arguments that if you leave the door to your house unlocked and I walk in uninvited then I'm still tresspassing, the house doesn't have to be locked for it to be breaking and entering. But what if you grab me and drag me into the house? If anything, my neighbors who are broadcasting their network across the property lines they are the trespassers. If I find a signal that is unencrypted and blasting unwanted into my house, then I say it's mine. What say you?
