Just a few miles from me, this guy got screwed for using someone's [open] wi-fi connection. Now, I know there are specific laws against this in many places, but it still just blows my mind.

Trespassing isn't trespassing if the door is open and no one's asked me to leave. Why is using someone's unsecured wireless connection worth US$10,000 and five years in jail?

[Ancient History]

<shrug> Depends on the jurisdiction. Usually, anybody on someone else's private property without permission (or specific exemption by law, such as meter readers and law enforcement during the course of their duties) is trespassing. Properly speaking, however, anyone that's nonviolent would only be opening themselves to a lawsuit, not charged with a criminal offense.

Of course, the idea of equating wi-fi access to trespassing is a bit of a false start. It's more akin to utilizing an unsecured resource, like taking a drink from somebody else's well.

[jo_alex]

WOW, that's quite a harsh punishment. I would expect to be fined maybe, but jail? Don't know what are the laws on that in Europe, but am now glad that I stopped using someone else's unprotected wi-fi connection some time ago. [/glow]

That is not the explanation that I have been given from the police. The explanation I have been given is that unless physical effort is required to enter [such as pushing open a door] you are not trespassing when entering a building. You are not trespassing on property unless asked to leave, or if in violation of clearly posted signs.

This many only be in my state, however.

I know this is the same in CO.

That is how I got the charges thrown out.

[WillyGilligan]

Definitely a harsh punishment, but I would definitely think that there should be some penalty for stealing bandwidth. That should be handled like AH says.

I really like his metaphor better than mine.

Strangely, I think responsibility for securing your wireless connection should lie with you [since it's your wireless connection], while responsibility for not taking water from someone else's well should lie with the water-stealer. [Little greek joke, there.] I guess this is why I think of it as trespassing [which it's not like] and not as resource-theft [which it is like]. Weird.

[FlakJacket]

Well for some reason I can't seem to get the link to work but whatever. The only two reasons why I can think of that this should be a major deal is if the owner of the Wi-Fi had a set ul-dl limit for the month which means that if you then use it you are then taking away something that they've paid for, or less convincingly if they both tried to use it at the same time thus slowing the connection speed for the paying customer.

[WillyGilligan]

Question: if someone steals your bandwidth and downloads a bunch of child pornography, or conducts some other form of mischief, would that be tracked to your house?

That would be breaking and entering (even pushing an open door further open counts). Yes, you are also trespassing and most likely will just get charged for trespassing.

You are not trespassing on property unless asked to leave, or if in violation of clearly posted signs.

...unless asked to leave by an agent of the owner (security, maintenance, etc) or by someone legally allowed to be there (employee, resident, etc).

Standard disclaimer: Your state may vary, this is how it works in Cali.

Oh absolutely. I "borrow" unsecure wireless connections all the time. I drive around my county for a living and I have my laptop with me.

You can secure your wireless connection and you can set it to not broadcast. If you chose to do neither, that's the equivalent of leaving the keys in the car and the windows rolled down. Don't be surprised if someone is surfing your open, unsecure wireless connection if you make it stupid simple for someone to do so.

While you shouldn't be surprised that someone steals your unlocked, key-in-ignition car or uses your open, broadcasting wi-fi; the person that takes advantage of your lack of security is still culpable for their actions. It's still theft, or should be, to take something that belongs to someone else without their permission, and the level of security used by the victim can vary for multitudes of reasons without changing that one simple fact.

Welcome to the fun, fun world of law being years behind technology and all the problems that arise.

Personally, I don't consider it theft, but I'm also biased...I use unsecure wireless internets.

[Adam]

Question: if someone steals your bandwidth and downloads a bunch of child pornography, or conducts some other form of mischief, would that be tracked to your house?

It could be, yes. Unless you take great efforts to only download from networks that specifically try to hide your network address, it can generally be discovered. From there, with a typical modem -> router -> computers setup, it's much more difficult to determine where the exact end destination [computer] was.

Some people actually use this as a reason to leave their routers unprotected, with the logic that if the police can't prove that their computer downloaded the material [because anyone could connect to their network], then they wouldn't be able to be successfully prosecuted.

[WillyGilligan]

I understand that it's a result of technology advancing faster than law, I'm just saying that the principles can still stand as new behaviors become possible. Stealing someone's bandwidth can be a very negligible thing, but it is a drain on the system that they pay for. It's mostly going to affect people with download limits and so on, but it's still theft to steal from people that theoretically won't miss it.

And I think that stealing bandwidth is an avenue for framing someone else's connection for your cybercrime. I'm not sure about the technicalities of that one, though, so if it's truly easy to defend yourself against an accusation of child pornography when the shit was downloaded to your house by someone parked nearby, then I might have less of a problem with it. The impression that I have is that the police would track you down by IP address and then confiscate your computer(s). If you don't have the porn, it'd be harder to prosecute you, but I honestly don't know what would happen.

It's similar to the idea of clamping down on illegal immigrants because any violation of the border makes it easier for more damaging threats to sneak in.

[MissTeja]

E - you may wanna check/fix the link.

I'm gonna find out tomorrow what the terminology is for trespassing. I think it's stricter than 'if they didn't ask you to leave and there's no sign saying otherwise, you can go onto people's property as much as you want'...but I don't think its as strict as 'you are not allowed to step foot on someone else's property without permission.'

I'll check.

[MissTeja]

Note, these are Michigan:

(There's a good few that deal with animals, but I'm leaving those out. Whole nother ball game if you trespass onto land with animals used for breeding (i.e. a farm) or if you let your animal run wild. There are also specific statutes for trespassing for eavesdropping purposes, laws about posting trespassing signs, etc., but I could write a book to list all the detailed laws.)

324.73102 Entering or remaining on property of another; consent; exceptions.

Sec. 73102.

(1) Except as provided in subsection (4), a person shall not enter or remain upon the property of another person, other than farm property or a wooded area connected to farm property, to engage in any recreational activity or trapping on that property without the consent of the owner or his or her lessee or agent, if either of the following circumstances exists:

(a) The property is fenced or enclosed and is maintained in such a manner as to exclude intruders.

(b) The property is posted in a conspicuous manner against entry. The minimum letter height on the posting signs shall be 1 inch. Each posting sign shall be not less than 50 square inches, and the signs shall be spaced to enable a person to observe not less than 1 sign at any point of entry upon the property.

(2) Except as provided in subsection (4), a person shall not enter or remain upon farm property or a wooded area connected to farm property for any recreational activity or trapping without the consent of the owner or his or her lessee or agent, whether or not the farm property or wooded area connected to farm property is fenced, enclosed, or posted.

(3) On fenced or posted property or farm property, a fisherman wading or floating a navigable public stream may, without written or oral consent, enter upon property within the clearly defined banks of the stream or, without damaging farm products, walk a route as closely proximate to the clearly defined bank as possible when necessary to avoid a natural or artificial hazard or obstruction, including, but not limited to, a dam, deep hole, or a fence or other exercise of ownership by the riparian owner.

(4) A person other than a person possessing a firearm may, unless previously prohibited in writing or orally by the property owner or his or her lessee or agent, enter on foot upon the property of another person for the sole purpose of retrieving a hunting dog. The person shall not remain on the property beyond the reasonable time necessary to retrieve the dog. In an action under section 73109 or 73110, the burden of showing that the property owner or his or her lessee or agent previously prohibited entry under this subsection is on the plaintiff or prosecuting attorney, respectively.

(5) Consent to enter or remain upon the property of another person pursuant to this section may be given orally or in writing. The consent may establish conditions for entering or remaining upon that property. Unless prohibited in the written consent, a written consent may be amended or revoked orally. If the owner or his or her lessee or agent requires all persons entering or remaining upon the property to have written consent, the presence of the person on the property without written consent is prima facie evidence of unlawful entry.

324.73110 Violation as misdemeanor; penalties.

Sec. 73110.

(1) Except as provided in subsection (2), a person who violates this part is guilty of a misdemeanor punishable by imprisonment for not more than 90 days or a fine of not less than $100.00 or more than $500.00, or both.

In addition, the court shall order the person's license revoked if the person is licensed to hunt, fish, or trap in this state, and shall order the person not to seek or possess a license for the remainder of the calendar year in which the person is convicted and during at least 1 succeeding calendar year. This subsection does not apply after September 30, 2001.

(3) This subsection applies beginning October 1, 2001. A person convicted of a second or subsequent violation of this part occurring within 3 years of a previous violation of this part shall be punished by imprisonment for not more than 90 days or a fine of not less than $100.00 or more than $1,000.00, or both. In addition, the court may order the person's license revoked if the person is licensed to hunt, fish, or trap in this state, and may order the person not to seek or possess a license for not more than 3 succeeding calendar years.

(4) The court may order a person convicted of violating this part to pay the costs of prosecution.

(5) The following may be seized and forfeited in the same manner as provided in chapter 47 of the revised judicature act of 1961, 1961 PA 236, MCL 600.4701 to 600.4709:

(a) A protected animal, a fur-bearing animal, game, or fish taken while committing any violation of this part.

And yet there are entire cities that are trying to create hot spots for WiFi. I think Philadelphia was one of the first, right?

Yeah, but not that well.

Illinois also issues fines for piggybacking.
