"If You Can Put It On A T-Shirt, It's Speech"
from the clear-as-mud dept.
Carnegie Mellon Professor David Touretzky testified before the court on this very issue. (See his Gallery of CSS Descramblers.)
Here's Touretzky being questioned:
19 Q. The next item, the DeCSS T-shirt, why did you post this on
20 the website on the gallery?
21 A. Well, this is a photograph of a T-shirt that's offered for
22 sale by an outfit called CopyLeft, and I purchased one of
23 those shirts myself. And the point of including it here is it
24 seems to me that there is some confusion among all the parties
25 in this case about whether something is speech or not.
1 And my reaction is if you can put it on a T-shirt,
2 it's speech. And so the point of showing the T-shirt was to
3 illustrate that and, also, to raise the question if this
4 T-shirt, itself, would have to be prohibited, then I wonder
5 what would happen to me if I wore the shirt in public.
6 Wearing the shirt in public could, perhaps, be interpreted as
7 engaging in trafficking a circumvention device.
8 So if one really wants to afford the plaintiffs the
9 protection that they seek, I think I would only be able to
10 wear my shirt in the privacy of my own home and must not go
11 outdoors with it.
Touretzky drew up a lengthy argument showing that if the DeCSS source code were banned, the only way to prevent that knowledge from being transmitted would be to ban it in all its forms - image file, various perturbations of the code into forms similar to plain English, annotated commentary, even on t-shirts and hidden in image files - all of these would have to be banned because the source code is easily retrievable from all of them. The Technical Term for this is "opening up a can of worms". Touretzky was trying to show the court that the issue was hardly open-and-shut - if you look at it one way, it's a device which can perform a task, but if you look at it another, it's speech that's expressive and communicative. If you're a programmer who's never taken much of a look at the legal issues surrounding computer programs, it may be patently obvious to you that code is speech, but to the judicial system, it is not so clear.
The judge was apparently much impressed, and started seriously thinking about the free-speech implications of banning DeCSS, possibly for the first time in the case. He seemed to take Touretzky's argument to heart - either all would have to be banned, or none. Apparently the MPAA took Touretzky's argument to heart as well, and they're therefore doing what is necessary to remain consistent with their argument: going after the T-shirts.
Maybe they'll go after the New York Times as well. Perhaps if the Times gets dragged into the case for posting an image of the illegal shirt, it might finally become clear to all and sundry that this case is about much more than copyright infringement.
Subject: [CAFE-News] EFF DeCSS Trial Summary
DVD Update: July 31, 2000
Universal City Studios et al v. 2600 Magazine
EFF DeCSS Trial Summary:
Facts in EFF's Favor as MPAA Claims Collapse Under Scrutiny
EFF defense team established a solid record at trial that the major film studios are attempting to use the DMCA to ban DeCSS so it can monopolize the DVD player market. Despite its immense investigative resources and months of effort, the MPAA was forced to concede at trial that it could not find a single instance of piracy related to the software. The First Amendment rights of all citizens have been endangered because of the studios' panic and over reaction.
Norwegian teenager Jon Johansen testified for the defense that he was working to build a DVD player for the Linux operating system when he posted the program to the LiVid list that he and two others authored. LiVid Project Leader Matthew Pavlovich testified that his development group used DeCSS to create a Linux DVD player that can compete with the studios' and DVD-CCA's current monopoly on DVD players. The studios were hoping to ban the software before a competing DVD player could be created that is not required by a CSS license to restrict features which allow people to exercise their legal rights. Journalist Emmanuel Goldstein, the editor of 2600 Magazine testified that he published the code in his reporting of Hollywood's crazed reaction to the software's existence, when the studios launched this legal attack against him.
The high point of trial was the electrifying testimony of Professor David Touretzky of Carnegie Mellon University's Computer Science Department, EFF's final witness before resting its case. Touretzky explained to the court how computer programmers use computer code to communicate to one another with precision. He showed the court how an injunction against DeCSS chills his ability to express himself. Judge Lewis Kaplan stated Touretzky's testimony was "persuasive" and "educational" and would likely change his First Amendment analysis of the case. The judge did not indicate that he intends to rule in favor of defendants however, and EFF is prepared to take an immediate appeal to the Second Circuit Court of Appeals. Trial briefs are due August 8 and a short turn-around is expected for a ruling.
After the close of trial, DVD-CCA filed a motion to intervene in the NY litigation to fight EFF's challenge to unseal the Xing CSS license entered into evidence. DVD-CCA has requested to keep its CSS license out of the public record and Judge Kaplan will accept papers opposing DVD-CCA's intervention and secrecy request until August 2 at 5p.m.

National secrets and free speech (Score:3)
Your point that not all speech is protected, however, is a good one. Speech that violates a contract is protected but can get you sued for breach of contract. But the bar for what speech is protected vs. not protected is rather high, and generally involves speech that has a likelihood of inciting violence or causing immediate harm to people. The bar is especially high when it is a media outlet involved, because you're not only dealing with free speech, you're dealing with free press, i.e., a double-whammy. I believe the judge in the EFF case has basically concluded that the code involved, as printed by 2600, is speech. However, he has asked the lawyers to make arguments as to whether it should be considered protected speech (bringing up the issue of the draft cards during the Vietnam era, where a judge says yes, burning them was speech, but it was not protected speech).

Software is not a product, its a medium of expression
Knowledge is expressed in it as much as in oral tradition (very perishable and difficult to transmit,[like documentation by osmosis,]) or the via the written word which at least persists but is passive and inert, software is an interactive means of expression.
Furthermore it is about as patentable, and copy- rightable as anyother human language. I don't think, despite possible protestations of those much parodied and maligned "upper-class twits" who speak with proper received pronunciation" that it can even be considered to be owner, since much as it is the result of consensual aggregation of linguistic rules and recognizable algorithmic process.
Software is a medium. It is used to express knowledge in a form which is efficient, or at least self-sufficient, and beyond active (unlike the passivity of words on a page or audiences in a theatre,) it is interactive.
The industry consortia are not about rights. They are about control but control is a double edged sword.
Start a copyright infringement suit against them about using the English language without having obtained written prior consent (one might ask from who and in what language and that's the point!

Of course, they might very well try to control the use of the language next but I don't think that a suit could be expressed that did not itself violate the nature of the suit.
They are trying to control what you see, hear, think for their own profits.
Stop paying them for a few weks and catch a live show or a play, read a book, watch TV and let the wind of change blow through record stores and movie theatres. Give the next block-buster a pass. You can live with the alternatives and wait until is comes back in video.

Out of all of the many, many ways that have been invented and discovered to decode CSS, the only one that is suitable for building a commercial unlicensed DVD player, without the player restrictions (Macrovision, no digital video output), is DeCSS.

2600 Magazine made a similar point when they wrote about what they would do if the judge issued an injunction requiring them to remove the code from their website. They wrote (paraphrasing): If we have to remove the code, we'll link to the code. If we have to remove the links, we'll write out the web addresses in ascii. If we have to remove the addresses, we'll display an image that contains the web addresses, if we have to remove that, we'll spell out the address (http colon slash slash www dot 2600 dot com slash (etc.)). 2600's point (Touretsky's (sp?) point) is that it'd be ludicrous to try and ban everything relating to the code for two reasons: persistant people (i.e. 2600) would find ways around it, and you'd have to create a virtual police state to enforce it.

The role of lawyers in corporations today is unfortunately too much focussed on making legal behaviors (free speech not the least) become very expensive ... you have to pay for your free speech, big time.
In the case of RSA, the US Govt applied this knowledge in two basic ways to slow down the spread of cryptographic technology ... likely a better approach than the media monopolies took, but I hope they don't find a way to do the same:
What it's really going to come down to is that the US government has to decide whether it wants its accomodation with media organizations to be more like that between governments (which let themselves curtail fundamental human rights because they're the cops, and dammit they don't like "those kind of people" at all) ... or instead to be like it's supposed to be, where individual rights are more than hot air.
The thing to really watch out for is when the Executive or Legislative branches start getting in bed with the multinationals. Oh wait ... that's like the DMCA helping Disney or Warner, isn't it? Or the office of Drug Policy engaging in media payola to get propaganda out, closly in cahoots with private organizations that gain financially by continuing the current generation's major Prohibition?
The Legislative and Executive branches have too many ways to prevent the courts from seeing their non-constitutional acts. And what we need to see, but won't, is the Judicial system ripping new orifices into those other branches for pulling so much crap.

First, we need an ACCESS PROTECTION DEVICE. Let's say that our access protection is to invert all the bits in a file: exchange 1's with 0's, and 0's with 1's. Now, we need a body of copyrighted works. I'm sure we could get some submissions, perhaps we could copyright an entire thread of petrified natalie portman spam. Finally, we distribute our body of copyrighted works with our ACCESS PROTECTION DEVICE engaged - we bit flip all the ascii. End step 1.
Step 2: create a license for authorized access to our copyrighted works. The license would be:
1) by viewing these works you agree never to file a lawsuit again, ever.
2) by viewing these works you agree to strip naked and run screaming down the street if we should ever call upon you to do it.
Now, the third and masterful step:
3) Encrypt the DeCSS source code using our bit-inversion ACCESS CONTROL DEVICE. Think about it - if they try to prove that we're distributing the code, then we can prove that they were in violation of the terms of our license (they sued us) AND we can charge them with trafficking in a device specifically designed for circumventing access protections to a body of copyrighted works!
Oh yes, we'd have them by the short curlies!
Then we could sue their fat asses.
The next step, of course, is to get the english language declared to be an access control mechanism, and license it. but first things first.
Of course it's ridiculous, but then hey, they're banning t-shirts and declaring martial law in seattle, so why the fuck not?

I can think of several things which fit these criteria and are still obviously wrong.

Free speech, protected speech, and consequences (Score:3)
I wonder what Touretzky would do if I printed up t-shirt's with all his credit card numbers, addresses, social security numbers and then sold them. By his argument it would be legal (and right) to do so, because he incorrectly believes that anything which can be printed on a t-shirt (regardless of how the information was gathered) can be freely given to the world without consequence.
Soooooooo many people here on /. seem to have a problem understanding that there is a difference between civil liabilities due to free speech and any restriction placed upon that speech. The example given by the previous poster is spurious at best; it would be perfectly legal to disseminate that information, provided that (a) no laws had been broken in obtaining it, and (b) no legally-binding restrictions were being broken in giving out that information. Are there civil repercussions for what people might do with that information? Hell yeah! Doesn't make it any less free speech, does it? Slander and libel are excellent examples - you're free to say/print what you want about a person/place/thing, but be prepared for the responsiblities and liabilities that your words might incur.
Free speech - as in protected speech - is expression that does not violate criminal statutes by its very existence; it's free speech to tell everyone your neighbor buggers his dog, if you didn't break laws finding it out. That doesn't mean that he doesn't have a right to sue your ass into the ground if it's untrue.
Missing the point of the story (Score:3)
Touretsky is being disingenuous in his testimony. Buying and wearing the t shirt is an act of political speech, predominantly for the purpose of protest. That's not the same thing as distributing something in a mass medium for the purpose of having it compiled. Moreover, it's not a very effective means of disseminating the putative violation -- somehow, I can't see ten million script kiddies buying their 133t s41rts and typing the code in by hand!
Those are key facts. If the primary purpose in disseminating something is to protest, then it might be (and, in my opinion, probably is) protected speech, even if it's facially a violation of DCMA. Even if it isn't protected, the inefficiency of the medium is a sufficiently high barrier that it would almost certainly be protected under the traditional doctrine of fair use.
Contrast this to the case in front of the judge. Corley and 2600 are alleged to have intended to disseminate a cracking tool. If the plaintiffs show that, the protected speech defense fails. Moreover, they were using a highly efficient technique to disseminate the item: first, the source itself, then, links to the source. So, the secondary "fair use" defence fails.
Judges and juries are capable of makng that distinction. It's perfectly reasonable that the t-shirt is protected from DCMA, but the program and the links are not.

Maybe eventually we can get rid of "programming patents", since all programming is expressible as a discrete system, and therefore can be formalized as math, and math cannot be patented.

Not Surprising (Score:4)
I don't think that this is surprising at all. There's the old saying, "In for a penny, in for a pound." If the MPAA is really serious that DeCSS is a threat to their business, they have to be serious about tracking it down in all of its manifestations. Hell, it was the defense that made that point to start out with- they've basically dared the MPAA to do this very thing by bringing up the issue of the tee shirts in court.
If the defense is going to stand up and say, in essence, that it's vital to stop the tee shirts for the injunction to mean anything, it's pretty silly of them to complain when the plaintiff goes ahead and does exactly that. Personally, I think that this is a great thing for the defense. The plaintiff is left in the rather difficult position of either refusing to take all steps necessary to protect themselves, in which case their seriousness has to be questioned, or of grossly overreacting by going after apparently trivial and silly violators. Of course it looks that way because it's true.
IMO, this is a great demonstration of what is really meant by the statement, "Information wants to be free." That's free as in speech, not as in beer. Once you let information out of your tight control, it's out of anyone's control; you can't prevent its unlimited replication.

Quote follows:
Thomas Jefferson to Isaac McPherson
13 Aug. 1813Writings 13:333--34
It has been pretended by some, (and in England especially,) that inventors have a natural and exclusive right to their inventions, and not merely for their own lives, but inheritable to their heirs. But while it is a moot question whether the origin of any kind of property is derived from nature at all, it would be singular to admit a natural and even an hereditary right to inventors. It is agreed by those who have seriously considered the subject, that no individual has, of natural right, a separate property in an acre of land, for instance. By an universal law, indeed, whatever, whether fixed or movable, belongs to all men equally and in common, is the property for the moment of him who occupies it, but when he relinquishes the occupation, the property goes with it. Stable ownership is the gift of social law, and is given late in the progress of society. It would be curious then, if an idea, the fugitive fermentation of an individual brain, could, of natural right, be claimed in exclusive and stable property. If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. Its peculiar character, too, is that no one possesses the less, because every other possesses the whole of it. He who receives an idea from me, receives instruction himself without lessening mine; as he who lights his taper at mine, receives light without darkening me. That ideas should freely spread from one to another over the globe, for the moral and mutual instruction ofman, and improvement of his condition, seems to have been peculiarly and benevolently designed by nature, when she made them, like fire, expansible over all space, without lessening their density in any point, and like the air in which we breathe, move, and have our physical being, incapable of confinement or exclusive appropriation. Inventions then cannot, in nature, be a subject of property. Society may give an exclusive right to the profits arising from them, as an encouragement to men to pursue ideas which may produce utility, but this may or may not be done, according to the will and convenience of the society, without claim or complaint from anybody. Accordingly, it is a fact, as far as I am informed, that England was, until we copied her, the only country on earth which ever, by a general law, gave a legal right to the exclusive use of an idea. In some other countries it is sometimes done, in a great case, and by a special and personal act, but, generally speaking, other nations have thought that these monopolies produce more embarrassment than advantage to society; and it may be observed that the nations which refuse monopolies of invention, are as fruitful as England in new and useful devices.
Re:Isn't this like PGP export? (Score:4)
The heart of the issue is the US
Export Regulations, which classifies
cryptographic software as
munitions(!). Thus you need a
license in order to export PGP from
the USA. However, the Export
Regulations only covers software in
electronic form (e.g. on disks, or via
the Internet). PGP 5.0i, on the other
hand, was compiled from source
code that was printed in a book (well, actually 12
books - over 6000 pages!). The books were exported
from the USA in accordance with the US Export
Regulations, and the pages were then scanned and
OCRed to make the source available in electronic
form.

There is a difference between a subpoena and a summons, the former being what compels testimony from a witness, the latter being what brings a person into a lawsuit as a party.
If we're talking about the New York DeCSS case, which just was tried, then it makes no sense that a new entity could be brought in as a defendant, after trial, especially since the issues surrounding distribution of printed source are quite different than those surrouning compiled object.
On the other hand, this could refer to one of the two other DeCSS cases, the ones in California and Connecticut, respectively, but the article gives no indication.
If anyone does know whether it is a subpoena or a summons, and in which case, please do post, because as a lawyer who has been following the cases, I am having trouble making any logical sense of this.
