Two Turntables and a Clipper Chip

Two turntables and a Clipper chip By Skinny DuBaud January 15, 1998 SAN FRANCISCO--In what certainly was not a hacker's delight, RSA Data Security CEO Jim Bidzos stunned the crowd at his company's annual conference this week as he joined old-school rappers The Sugar Hill Gang for a detourned version of da Gang's classic, "Rapper's Delight." Well aware that he's no Kool Moe Dee, Bidzos hip-hopped his way through the modified lyrics, which contained such sparkling couplets as... "They once proposed a thing called Clipper Now there's something new that ain't much hipper Key recovery won't work, so the experts say But the government wants to push it on us anyway" and "I like hip hip hop I like to online shop I trust RSA To keep the hackers at bay" ...then promised never to pull such a stunt again. The RSA conference audience of crypto-math geeks, cyberlibertarians, and snoop-dogs cheered, of course. They'd throw their hands in the air (and wave them like they just don't care) for a wet sponge if it smelled antiauthoritarian, but many breathed a sigh of relief. Despite the awkward moments, Bidzos, who's made quite a name for himself as a public enemy of the federal government's restrictions on the export of encryption software, looked mahvelous sporting a fresh Van Dyke facial-hair arrangement on his prizefighter's mug. He apparently grew the ensemble to match the Sugar Hill Gang--in appearance at least, if not in dope MC talent. Always the suave host, Jim will be back among his tribe at the end-of-conference gala, for which the company has rented out the California Academy of Sciences in Golden Gate Park. The Skintelligentsia certainly will be there looking out for any representatives of Pretty Good Privacy, the crypto company enmeshed in legal battles with RSA. The PGP-brains don't have a booth at the RSA conference this year, but in celebration of their merger with Network Associates--the newly formed utility software company, that is, not the PR agency--they managed to throw a soiree last night at the Marky-Mark Hopkins Hotel, right across the street from the RSA proceedings at the equally fly Fairmont. Speaking of snubs, crypto rivals VeriSign and GTE, whose booths at the Fairmont were practically alongside one another, have been playing a bit of one-upmanship recently. Certificate authority (CA) VeriSign uses hardware storage from BBN to safeguard software encryption keys at its Silicon Valley offices. The hardware--which looks like small blue boxes about the size of a desktop telephone set--is the crypto equivalent of a strong box, ostensibly impervious to hackers. But BBN was recently bought by GTE, which owns rival CA Cybertrust Solutions, and all of a sudden, VeriSign isn't satisfied with the "performance" of those little blue boxes. The company has started looking elsewhere for its strong-box solutions, according to a Skinside source. How will users of encryption trust the "trusted third parties" if the trusted third parties don't trust each other? Staying in Baghdad by the Bay, the conspiracy birds are clacking their beaks over the latest public transportation developments. S.F.'s Municipal Railway (or "Muni," as the local posse calls it) has just opened an extension from the end of Market Street down to Willie Mays Plaza, now just a gaping pit where the new baseball stadium will spring up by the year 2000. The shorthand for the new rail spur? "MMX," short for Muni Metro Extension. Sure, the project's gone over budget, but I swear it fixed that floating-point problem years ago... Speaking of Big Willie Style, San Fran's mayor Willie Brown--who looks great in a fedora, I must say--may be second only to Bill Gates when it comes to haughty treatment of minions, but do Willie's employees sit on Thai temples and proclaim their divinity? That's apparently what happened to a Microsoft programmer on vacation. According to email making the rounds among MSN and WebTV employees, the young fellow (who didn't answer his Redmond phone when my agents rang him up) overheated his circuits, perched himself atop an ancient Thai temple for 10 hours, and told the authorities he was God. It took scaffolding and a special police neck-hold to bring him down, according to the report. Brutal, Juice, brutal! Whether the item is true or not, it produced some amusing comments as it made its way through the outer provinces of Lawrence Lessig's favorite evil empire. "So, um, how closely are we supposed to try to blend into the Microsoft culture?" mused one WebTV employee as the tidbit made its way around the company. "I'm sure that each of us, at one time or another, has had the experience of waking up in some God-forsaken tropical paradise and feeling that horrible falling sensation that comes from being separated from your desk and workstation," wrote another Webhead.

What does the Declaration of Independence actually consist of? Sure, from our school days, we may remember that "these United Colonies are, and of Right ought to be, Free and Independent States." But that's only the last paragraph. Prior to that, Mr. Jefferson and his co-signers spent 29 paragraphs doing ... what? "Declaring their causes," of course! We did this -- anyone would have the right to do this -- because of a "long train of Abuses and Usurpations," remember? "He has erected a Multitude of new Offices, and sent hither Swarms of Officers to harrass our People, and eat out their Substance." Remember? "He has kept among us, in Times of Peace, Standing Armies, without the consent of our Legislatures. "He has affected to render the Military independent of and superior to the Civil Power. "He has combined with others to subject us to a Jurisdiction foreign to our Constitution, and unacknowledged by our Laws; giving his Assent to their Acts of Pretended Legislation: "For quartering large Bodies of Armed Troops among us: "For protecting them, by a mock Trial, from Punishment for any Murders which they should commit on the Inhabitants of these States. ..." This is not just schoolboy stuff. A message etched in fire from our patrimony, these words tell us how Americans shall know when they are again justified in declaring themselves free of a parasitical tyrant. Fast forward 216 years, to the late summer of 1992. Part-time gunsmith Randy Weaver had failed to show up for a court date, after being entrapped by ATF agents hoping to turn him into a snitch, to spy on a nearby CHURCH. Federal marshals now trespass on the Weaver family's private Idaho property (the marshals carry no warrant this day and are not there to make an arrest), and open fire when they're spotted by the family dog, killing the dog, and also Weaver's 14-year-old son, Sammy. A federal marshal is also killed, either in self defense or by fratricidal fire. (The federals never release any shell casings or autopsy results for independent review -- but a jury acquits Weaver and family friend Kevin Harris in the death.) The federal government answers by flooding the property with hundreds more trespassers in full combat gear. FBI sniper Lon Horiuchi then shoots at Weaver and Harris as the pair races back to his front door, after paying their respects to young Sammy's body in an outbuilding. One of Horiuchi's shots passes through the window of the kitchen door, shooting away much of the brain of Weaver's wife Vicky, for whom there are no warrants outstanding. At the moment prior to her death (which comes after 30 seconds of blood-curdling screams), Vicki Weaver was holding her baby in her arms in her own kitchen, threatening no one. Unaware they have murdered Vicky Weaver, federal agents continue to shout taunting remarks at her dead body, in the full hearing of her children, for days. The federal government eventually pays Weaver -- acquitted of murder and all other major charges -- and his children $3.1 million in damages for these wrongful actions. After a year-long review, the U.S. Justice Department decides in 1994 not to charge sniper Lon Horiuchi with any crime. Like the Germans at Nuremberg, they declare he was "just following orders." But, just before the five-year statute of limitations is due to toll, in August of 1997, Boundary County (Idaho) Prosecutor Denise Woodbury bravely files a charge of involuntary manslaughter against this armed trooper, who has long been quartered among us as part of the 60,000-strong federal "standing army" of FBI, DEA, ATF and other Einsatzgruppen troopers. Here now is the vital test. Will this "king's officer" be allowed to stand trial on the evidence, before a randomly selected jury of Idahoans, in their own state court? Or will the new king "protect him, by a mock Trial, from Punishment for any Murders which he has committed on the Inhabitants of these States"? Jan. 7, 1998: The Associated Press informs us: "BONNERS FERRY, Idaho (AP) -- A judge today ordered an FBI sharpshooter to stand trial on a state manslaughter charge for the death of white separatist Randy Weaver's wife in the 1992 siege at Ruby Ridge. ... "Magistrate Judge Quentin Harden ... scheduled a Feb. 13 arraignment before state Judge James Michaud." So far so good. But now the inevitable: Jan. 12, 1998: "BOISE, Idaho (AP) -- FBI sharpshooter Lon Horiuchi won his bid today to be tried in federal court on the state charge brought against him in the death of white separatist Randy Weaver's wife in the 1992 siege at Ruby Ridge. ... "Horiuchi, supported by the U.S. Justice Department, petitioned the federal court to take over the case on grounds that the transfer is allowed when federal agents are prosecuted for conduct in their official capacity. "U.S. District Judge Edward Lodge agreed. ... Neither murder nor manslaughter, of course, is a federal crime. State courts have sole jurisdiction to try such cases. Clearly, the federals want jurisdiction here so they can either dismiss the case, or (if a public outcry renders that unwise) so limit the evidence admitted that the question to be decided ends up nothing more than "Was Agent Horiuchi obeying what he believed was a lawful order at the time?" Sort of like letting Martin Borman set the ground rules for the Nuremberg trials. Modern federal judges -- like Judge Smith in the trial of the Waco survivors -- are famous for declaring "The United States government isn't going to be put on trial in my courtroom." As one of my e-mail correspondents puts it: "The test for whether one is living in a police state is that those who are charged with enforcing the law are allowed to break the laws with impunity." This -- along with Janet Reno and her Waco Killers still roaming free, of course -- is the great modern test of whether this Union can long endure. If Lon Horiuchi walks (or even if some untimely "accident" allows him to escape justice) while the surviving VICTIMS of the federal assault at Waco are still serving long prison terms, after being found INNOCENT of all major charges, then what shall we say to the patriot who advises: "If you see a federal agent committing a crime, don't bother turning him in, just shoot him down like a dog. Kill him on the spot, and walk away without giving it a moment's thought." Showing our respect for due process, do we continue to say: "Oh no, that would be wrong. Just turn him in to the proper authorities, and justice will be done"? Do we, really? Vin Suprynowicz is the assistant editorial page editor of the Las Vegas Review-Journal.

Privacy as Censorship -- Cato Institute policy analysis
by Declan McCullagh 17 Dec '03

17 Dec '03

If you care about electronic privacy, read this new report. It correctly says that many proposals to create new "privacy rights" become censorship by another name. The paper is at: http://www.cato.org/pubs/pas/pa-295.html -Declan ******* http://www.cato.org/pubs/pas/pa-295es.html PRIVACY AS CENSORSHIP: A Skeptical View of Proposals to Regulate Privacy in the Private Sector by Solveig Singleton (solveig(a)cato.org) director of information studies at the Cato Institute. Executive Summary Some privacy advocates urge the adoption of a new legal regime for the transfer of information about consumers among private-sector databases. This "mandatory opt-in" regime would require private businesses to ask for a consumer's permission before trading information about that consumer, such as his buying habits or hobbies, to third parties. This would, in effect, create new privacy rights. These new rights would conflict with our tradition of free speech. >From light conversation, to journalism, to consumer credit reporting, we rely on being able to freely communicate details of one another's lives. Proposals to forbid businesses to communicate with one another about real events fly in the face of that tradition. New restrictions on speech about consumers could disproportionately hurt small businesses, new businesses, and nonprofits. Older, larger companies have less need for lists of potential customers, as they have already established a customer base. We have no good reason to create new privacy rights. Most private-sector firms that collect information about consumers do so only in order to sell more merchandise. That hardly constitutes a sinister motive. There is little reason to fear the growth of private-sector databases. What we should fear is the growth of government databases. Governments seek not merely to sell merchandise but to exercise police and defense functions. Because governments claim these unique and dangerous powers, we restrict governments' access to information in order to prevent abuses. Privacy advocates miss the target when they focus on the growth of private-sector databases. To view the entire document: http://www.cato.org/pubs/pas/pa-295.html

Will bureaucrats turn the Net into TV? Note from FCC
by Declan McCullagh 17 Dec '03

17 Dec '03

A note from an acquaintance formerly at the FCC. --Declan ---------- Forwarded message ---------- Having spedt my years at the FCC doing pre-repeal Fairness Doctrine and Sec. 315 equal time matters, I think [deleted-dm]'s concerns, tho' justified politically [because most adminsitrations will leave no good technology unhobbled] are without substantial legal basis. The hook for the Fairness Doctrine obligation imposed on broadcasters as a corollary to their statutory 'public interest' obligations was as a licensee of scarce broadcast spectrum--a discrete frequency awarded on a putatively compettive basis. Those key elements[scarcity/license/obligation] are--for now--lacking in the on-line environment. And while no doubt this or another Administration, or wiley Congressional staffer could gin up a plausable nexus between the web and interstate commerce, sufficiient to sustain a new public interest obligation, I think we're two or three generations of bandwith scarcity away from that becoming a compelling element of a cyber-resource allocation scheme. Without that overarching allocation-based [license] compulsion (to force even facial compliance with an obligation, so that enforcement would become essential to compliance, thus creating a need for thousands of Web police to review commercial licensees sites and traffic--[what a nightmare] -) -the liklihood of developing a meaningful scheme of public interest obligation would be a an overdebated and overhyped PC exercise, quickly becoming comic--and then dangerous.
