um, no?

they raided his house because of child pornography.

that he had a Tor node and that fact got him off the hook is the part that needs more analysis. How do we know he doesn't operate the node for the very purpose of watching kiddy porn go by? Shouldn't everybody interested in child pornography operate their own exit node just for this purpose? Keep the kiddy porn collection in RAM for viewing whenever, then give the police the in-RAM-kiddy-porn-deleter password...

I understand that ghkbrew (and MANY other people here, not picking on you) subscribe to the idea that there should be untraceable currency, perfect privacy delivery mechanisms, etc.

But there are other people who live in the same democratic country that like the idea that somebody who bombthreats can be found.

I understand the issues on both sides, and I don't mind there is a spectrum of beliefs and a discussion. But it's so annoying when people write posts slanted like yours that they don't acknowledge the obvious "other side".

I read/heard something that David Mamet said, that he learned from the study of Jewish law (but it would apply everywhere) that in order for you to have the basis to discuss an argument with the other side, you need to be able to state the other side's argument in a way that the other side would not disagree with, then you get to make your point.

I thought that was a nice idea.

> "you need to be able to state the other side's argument in a way that the other side would not disagree with"

I particularly like a version of this termed the "Ideological Turing Test". The idea is to anonymously write both your position and an opposing position, and to see if an audience consisting of people from both sides (and, potentially, those who are neutral or are on some other side) can identify which side you actually support. If you can state both arguments convincingly enough that it's difficult to determine which one you really believe, then (according to adherents of this concept) you've earned the right to be critical. If, on the other hand, one side easily identifies you as an outsider, then you require further listening/study before you'll be capable of criticizing that side on a reasonable level.

While I think the process is more cumbersome than necessary, I agree with the underlying concept -- if you can't state someone else's argument in a way that they think is fair, then you either don't understand it well enough, or you understand but you're being intentionally disrespectful by choosing unfair characterizations.

This is brilliant, I love it.

There are often more than two sides though. You have to draw the line somewhere. There is a limit to how far this logic will go.

You only need to be able to understand a valid argument. The problem is that everyone will evaluate "valid" by their own beliefs and worldview.

Re:Tor exit node operator gets raided by police by MichaelBurge on Tuesday April 05, 2016 @04:48PM (#11434275)
Checking the validity of an argument is like typechecking: It's mostly mechanical and catches a large class of errors.

But there are some it doesn't catch. This is a valid argument:

    All animals live on Mars.
    All humans are animals.
    Therefore, all humans live on Mars.
Re:Tor exit node operator gets raided by police by skissane on Tuesday April 05, 2016 @07:41PM (#11435487)
The point being (which we both understand, but not everyone here does) is that in logical terminology, a "valid" argument is one whose conclusions must be true were its premises all true. That is a valid argument, even though its first premise is obviously false, because were its premises true, then its conclusion must be true. A valid argument whose premises are all true is a "sound" argument. But, while philosophers and logicians respect this "sound"/"valid" distinction, in popular usage the word "valid" is used to mean "sound".

Re:Tor exit node operator gets raided by police by icebraining on Wednesday April 06, 2016 @04:00AM (#11437352)
IIRC, in logic, an argument is essentially a function that takes premises and produces a conclusion. It's valid as long as the conclusion follows from the premises. The catch is that an argument being valid is not the same as the conclusion being true.
Re:Tor exit node operator gets raided by police by philipov on Tuesday April 05, 2016 @07:43PM (#11435504)
That is not a valid argument, because all animals do not live on mars. Your premises have the wrong type, and you have abused them to reach a fallacious conclusion.

This is what you meant to say:

    Suppose all animals live on mars.
    Suppose all humans are animals.
    Therefore, if all animals live on mars, then all humans live on mars.
This argument passes the type-checking test, and is indeed valid.
Re:Tor exit node operator gets raided by police by Pyxl101 on Wednesday April 06, 2016 @08:34AM (#11438308)
You are confusing the distinction between validity and soundness.

> That is not a valid argument, because all animals do not live on mars

It would be more accurate to say that it is not a sound argument because all animals do not live on mars. Validity relates to whether the conclusions follow from the premises, not whether the premises are true. (There are more constraints than that, but that's the basic version.)

Re:Tor exit node operator gets raided by police by philipov on Thursday April 07, 2016 @08:17AM (#11446620)
I am aware of the distinction between soundness and validity, but logic has strict types. I am referring to the type of the conclusion being wrong. "Therefore, all humans live on Mars" is not a valid conclusion from those premises if their truth value is not established. One must conclude the entire proposition "Therefore, if all animals live on Mars, then all humans live on Mars" for the argument to be valid.

Our strict types are Fact, Hypothetical, and Implication. It is only valid to use possibly unsound premises if you admit their type as Hypothetical and not Fact. If our argument includes premises of type Hypothetical then it is only valid to make conclusions of type Implication, which have the form "If <Hypotheticals are True> then <Fact>."

Disguising Hypothetical-type premises as Fact-type, and using that to draw conclusions of type Fact instead of type Implication is how people create strawman arguments in bad faith, and can be prevented at the validity-checking phase by enforcing strict typing.

Re:Tor exit node operator gets raided by police by icebraining on Wednesday April 06, 2016 @04:02AM (#11437359)
Nah, the type is correct, it's just that the value is false, hence the conclusion will also be false, even for a valid logical argument.
Re:Tor exit node operator gets raided by police by philipov on Thursday April 07, 2016 @08:29AM (#11446684)
I mean the type of the conclusion is wrong. If our argument includes premises of type Hypothetical then we may only make conclusions of type Implication, of the form "If <Hypotheticals are True> then <Fact>."
Re:Tor exit node operator gets raided by police by pc2g4d on Tuesday April 05, 2016 @03:47PM (#11433733)
If the exit node only permits HTTPS connections out of it then it would be impossible for him to view the contents of exiting traffic, right? That one restriction would seem to absolve the operator of responsibility for the contents of the communications.
Re:Tor exit node operator gets raided by police by zanny on Tuesday April 05, 2016 @03:55PM (#11433804)
Except the communications were going through TOR in his house. If police traced the packets exiting from him, that means they already got the public IP server the porn was sent from or to, but it passed through his computer as the visible endpoint.

That meant it either proceeded elsewhere on the TOR network or stayed on his machine, and they had no external way of knowing without checking his hard drives.

Re:Tor exit node operator gets raided by police by jandrese on Tuesday April 05, 2016 @04:48PM (#11434274)
The most likely scenario is that the Police were running a honeypot and tracing every IP that connected to it. Obviously this would pick up a lot of TOR exit nodes. One of the exit nodes is in their jurisdiction so they pay it a visit on the longshot chance that the exit node operator was also a pedophile.

If they knew he was running an exit node it smells a bit like a fishing trip, but since they didn't send the SWAT team in through the windows and hold his computers for 4 years out of spite (the Steve Jackson treatment) I have trouble faulting the cops too badly.

They did know. Martin Kaste of National Public Radio [reported](http://www.npr.org/sections/alltechconsidered/2016/04/04/472...), "Seattle police spokesman Sean Whitcomb says the department understands how Tor relays work, and they knew Robinson was a Tor host."

To support a warrant, the question has to be the other way around. As with any activity the could be in proximity to illegal activity, it's not, by itself, evidence of anything.

Re:Tor exit node operator gets raided by police by TeMPOraL on Tuesday April 05, 2016 @07:53PM (#11435564)
Tor network has only become "a thing" (as opposed to US military toy) only in the last few years. Half a decade ago such a log the police saw would probably be a clear-cut case of someone downloading or uploading child porn on the guy's network. Even with Tor being available, it's still worth checking out.
Re:Tor exit node operator gets raided by police by Zigurd on Tuesday April 05, 2016 @08:28PM (#11435723)
If they were that incompetent about computers they had no business running their own cp investigation. They would have mishandled evidence. They should have handed it off to the state police or the FBI.

Alternatively they could have just been bunch of dicks out to intimidate someone.

"How do we know he doesn't operate the node for the very purpose of watching kiddy porn go by"

Why would anyone do that? If he knows how to install Tor, why wouldn't he download it through somebody IP instead of his own? I can't see any technical advantage to downloading it using your own IP when you could use somebody elses...

Re:Tor exit node operator gets raided by police by icebraining on Wednesday April 06, 2016 @04:09AM (#11437391)
It'd make sense if he didn't trust Tor to actually anonymize his connections.
Re:Tor exit node operator gets raided by police by mike-cardwell on Thursday April 07, 2016 @11:20AM (#11447933)
If Tor isn't effectively anonymising connections, then he's screwed whether he downloads it from somebody elses IP, or his own...

Download from somebody elses IP = Probably not at all associated with himself.

Download from his own IP = Definitely associated with himself.

Again. What would be the advantage of doing this? There isn't one...

Re:Tor exit node operator gets raided by police by icebraining on Thursday April 07, 2016 @04:57PM (#11450657)
The post you've originally replied to said "watch the CP go by". Someone else would fetch it over his exit node, giving him an alibi, and he would just keep a local copy as it passed through.

This a great way of phrasing what I'd been thinking about as "arguing from someone else's shoes".

Its a truly terrible idea, and not surprising that it stems from someone who found religion worth studying. There is no need to delve into the depths of minutia to dismiss baseless arguments. If you argue that Spiderman is real, and he lives at the Justice League, I don't need to study canon of Marvel comics in order to deal with your argument.

Re:Tor exit node operator gets raided by police by omegaham on Tuesday April 05, 2016 @04:44PM (#11434239)
All he's saying is that you need to qualify what exactly the other person is arguing before you start arguing against it. It's a way of preventing strawmanning - you want to get the other person's central viewpoint out in the open, naked and unafraid, so that there is no ambiguity when you make your case. I don't usually do it, mostly because it's patronizing if the point is obvious, but I will do it if the person's argument is convoluted.

> someone who found religion worth studying

Like it or not, religion has been a cornerstone of history and civilization for about as long as there has been history or civilization. Secularism is a relatively recent invention, and secularism's influence has only been really felt in the last 50 years or so.

Religion is history, and history is definitely worthwhile to study.

Re:Tor exit node operator gets raided by police by lotharbot on Tuesday April 05, 2016 @05:50PM (#11434818)
> "you want to get the other person's central viewpoint out in the open, naked and unafraid, so that there is no ambiguity when you make your case"

Related: you want to face the other person's central viewpoint in its strongest form ("strongest" in the sense of being the best or most compelling variant, not necessarily the variant which has the most supporters or the most vocal supporters.) This is in both sides' best interest, provided both are honest in their motivations.

If someone believes something that's not true, but you only "take down" a misrepresentation of their false belief, you haven't actually helped them, because they know you didn't answer their actual position. It may even strengthen their false belief, because they now have the experience of someone claiming to be able to criticize their position but failing to do so, which they may generalize to "critics of this position have no real argument".

And if someone believes something that is true, but you are able to show a misrepresentation or a weaker formulation of it is false, you haven't done yourself any good. You've missed an opportunity to learn something true, by distracting yourself with a superficially similar position that you can dismiss.

Re:Tor exit node operator gets raided by police by tunesmith on Wednesday April 06, 2016 @12:26AM (#11436599)
I think there's one exception, and that's the (very common) case where the arguer is leaving their point open to implication and then refuses to explicitly make it. The wink wink nudge nudgers. Then if you try to pin them down, they keep weaseling out of it while continuing to almost make their argument. After a point you just stop engaging them.
Re:Tor exit node operator gets raided by police by tremon on Tuesday April 05, 2016 @05:50PM (#11434815)
Religion is history

That's a dangerous statement to make. Yes, religion has been hugely influential across societies. But religion has been equally succesful in rewriting history to suit its narrative.

I suspect religion has destroyed as much history as it has informed.

You did not understand. Nothing about the GP's position states that you should make your opponent's case for him. In fact, you already met the criteria if your opponent does not disagree with your assessment that he "argues that Spiderman is real, and lives at the Justice League".
