  1. Doh! on Government to Eavesdrop on Lawyer-Client Conversations · · Score: 1

    I'm proud to admit that I stand corrected. My parsing of the Fifth Amendment was incorrect and I'm embarrassed to have to blame sleep deprivation as the cause.

    I do stand by my assertion that the first amendment is being violated when valedvictorians are told that they cannot offer prayers at graduations and such, as this is clearly infringing on their right to practice their religion freely.

    It is my understanding that in many trial cases, much evidence is discovered that ultimately will never be used in a trial. Much of this is because the evidence is useless, but in quite a few cases, a judge will rule that the evidence is inadmissable for other reasons. Prior convictions and confessions under duress come to mind immediately.

    I can see no reason for wiretapped conversations between counsel and a client to be admissable in any court for the currently accused or any of his accomplices. That is not to say that I see no value in having these conversations taped.

    The crux of the problem that investigators are having now is the fact that none of the detainees with strong associations to the hijackers or other known terrorists, are saying anything. Anything that they may tell their attourneys would not be admissable in their trial, and their counsel cannot divulge much of this information anyway. Even though the eavesdropping tapes would be inadmissable in court, they could still provide leads for other investigative teams to persue on other linked individuals.

    Note that these individuals have had warrants issued, based on credible evidence. Many are direct accomplices to the events of 9/11. Our Bill of Rights does not say "presumed innocent" it only guarantees a fair trial, so that they can be convicted of only the crimes that they did commit. Many of them are not completely innocent people, and most who are really innocent know information about the truly guilty. Silence and priveledge are preventing justice from being done.

    I shouldn't respond to AC's but...

    I was one of the few in my high school class, many years ago, who didn't sleep through the "Rights vs. Priveledges" lecture. Were you?

    A right is something that is believed (in most cultures) to be "inalienable" or inseperable from being. Personal rights are not granted but are guaranteed by our U.S. Constitution and the Bill of Rights. Freedom of speech, freedom from persecution and freedom to bear arms are the most well known of these. Most of the other items in the Bill of Rights pertain to rights of people held for trial, and protection of their property and reputation (until found guilty).

    The tenth amendment stakes out the rights of states to override federal powers, when such powers are usurped outside of the constitution, hence some footing for the States vs. Microsoft case, but the seventh amendment should guarantee Microsoft a jury trial since the alleged offense is valued at greater than $20, and the eighth prohibits cruel punishment or excessive fines (a double edged sword for Microsoft).

    A priveledge is something completely different. It is not enumerated in the Constitution or the Bill of Rights. You can check, Lawyer-Client priveledge is not in their. Priveledges are manifestations of custom that are expected, but not guaranteed.

    Separation of church and state is one of these priveledges. If you check, you will find the Bill of Rights expressly says "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof;"

    What this means is that a state religion cannot be established, but that no laws can prevent someone from praying in public. The removal of all things with religious connotations is a priveledge extended to the ACLU and litigious agnostics, and actually inpinges on a constitutional right. Even some rights guaranteed by the Bill of Rights have loopholes that make them more priveledge than right. The third amendment, preventing the forced harboring of soldiers has exception provisions for times of war.

    This brings me to the infamous Fifth amendment and it's counterpart the sixth. These are the two you site, the ones which have the strongest of weak ties to attourney-client priveledge. So that no-one can argue baselessly, I'll provide the text here:

    Amendment 5

    No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.

    Amendment 6

    In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defence.

    There's a lot of verbage to parse there, but you can plainly see that the word lawyer, attourney, barrister, soliciter, ombudsman, or advocate are nowhere to be found! "Assistance of Counsel for his defense" is provide for, but no additional explicit rights are granted. Remember, presumption of innocence is not the right, a fair trial is. The presumption of the framers is that this would be used to protect the falsly accused, not the truly guilty. Also, a clause is contained explicitly permitting the removal of this right for military persons and for everyone in time of war or "Public Danger".

    In this sense, this eavesdropping is explicitly constitutional.

    Everyone should take a deep breath and remember these points:

    1. The fifth amendment will protect you if you committed a crime and told a lawyer about it while somebody was recording, as you cannot be "forced" to incriminate yourself.

    2. Such "testimony" will greatly aid the search for accomplices when lawyers cannot divulge such information.

    3. Priveleges are not rights. The ACLU is currently inventing the constitutional right of Lawyer-Client privelege when non-such right or privelege is given by the Constitution of the US.

    4. Many of those detained in this current action, are not citizens of the US, and do not have the same rights.

    5. In almost all true professions, Law and Clergy being the exceptions, practitioners are bound by codes of ethics that demand action when the safety or welfare of other human beings is at stake. Coincidently, this exception drives many lawyers and Priests to alcoholism, and other vices, but that's another post.

    I'm not lying and latency problems are not "totally program dependent."

    RISC takes many more instructions to do the same thing as a CISC chip, so caching the instructions will improve the performance for repeated actions. The P4 is RISC like on the chip level, so it would probably benefit from a much larger cache. I believe that the size of it's cache has less to do with the fact that it's low latency than it does with chip yields for making memory that runs reliably at 2Ghz.

    I will concede that some programs would definately show the large cache as superior to a small low latency cache. Witness the older SPEC benchmarks which became obsolete when they would fit entirely into the L1 and L2 caches of some processors. In this case, the large cache is superior to the small low latency cache.

    Think about what these processors will be used for. Most likely, they will be used for large database servers, as that is what HU-UX is good for. While an entire database will not fit into 32 Meg, a lot of repetitive queries and essential system and program code can fit into this large cache. In this way, this processor would be superior to a raft of P4's which would be constantly fetching from main memory for this particular type of service. So the first search for "Pam Anderson" web sites would take the same amount of time on a P4 as it would on this PA-8800, but every successive search would have a much higher possibly of being a cache hit on the PA-RISC chip.

    I agree completely that waiting for main memory is a huge problem.

    The latency issue just isn't an issue with the SPARC, or any other modern RISC-ish architectures. Out of order execution and branch prediction techniques can accomodate latencies. Cache size though, is much more important, as a larger cache can hold many queued instructions and data, which will be fed in a constant stream to the processor without having to revert to slower memory.

    In the P4, 20 stage pipeline and it's prediction logic are much more succeptible to cache latency problems. Waiting two or three cycles for data on a P4 could cause major pipeline hiccups.

    It occurred to me that in these troubling times, it could be a golden business opportunity to provide the services of enjoyable body searches for patron conscious event holders! Kind of like a walk through spa service that would make people feel good about being searched.

    Seriously, I doubt that whoever the guard was that did the search actually suspected your sister of harboring anything dangerous or of being a terrorist. Was she searched in the name of fairness to avoid the appearance of racial profiling (justified discriminitory searches), or was this a more typical search done for out of venue refreshments?

    Earlier this year, the PNC Park baseball stadium opened in Pittsburgh. Many people went to the games carying coolers of drinks, only to have them stripped at the gates. The old venue, Three Rivers Stadium, allowed fans to bring their own refreshments. The new one resorted to body searches for food and drink that were being brought in to avoid the exorbitant prices charged by the stadium vendors. After public outcry and several changes to the stadium's policy, some beverages were allowed in.

First, it would be accomodating a standard that many peripheral manufacturers would be supporting for LOW speed hardware. Second, it would be including it to showcase Firewire's supremecy as a HIGH speed interface.

    Remember, Intel has bee trying to market USB 2.0 as a FireWire killer. Everybody knows that the 480 Mbps spec. makes 1394's 400 Mbps look slower. Unfortunately for Intel, USB is a poorly hacked technology which is not capable of producing real-world results of this speed. Theoretically, it works this fast, until you add a slow device like a mouse or keyboard, peripherals which predominate the USB connected equipment today.

    Actually, they might use USB 2.0 for some integrated telephony and modem type devices, as that is what USB was originally developed for.

    Primarily, Apple would include the technology to maintain a pool of peripherals, since 2.0 devices will not work on 1.x buses. It will not be able to replace FireWire for high speed stuff, so they wouldn't be dropping 1394, even to save a few bucks on low-end models, since the "Digital Hub" requires high speed DV capabilities.

To put this in perspective, this single order was close to a year's production for the entire world-wide market for these incubators. These devices are not for any human (post-natal) incubation, but for bacterial and viral culturing, and can be used for no other purpose.

    Many people at my facility were conflicted. Locally, our economy was very poor, and passing on the order would mean layoffs. The higher-ups, looking for the quick money, were looking to sell them through Germany, if the commerce department didn't approve the sale. Clinton's dept. of Commerce wasn't known for their moral fortitude, and it did approve the sale. After the sale was completed and delivered, Iraq ordered enough spare parts to completely rebuild 1/3 of the incubators that they bought!

    To get Israel and the PLO on the same team in a war against terrorism, you would need some severe concessions. Israel would have to agree to not attack any Palestinians, where the consequence would be elimination of all US aid (guaranteeing a short lifespan for the state). Also, the Palestinians would have to agree to not attack any Israelis, or be considered a terrorist state, and be wiped off the face of the planet.

Eventually, you may find yourself nudging the controller and then waiting to see that you overshot your desired position. Of course more RAM, faster processors, and most importantly better graphics cards will greatly reduce this problem.

    Which OS and program are you looking at using? Most commercial 3D stuff has hooks into the OS level drivers for these devices. Also, most 3D input devices support a wide range of UNIX operating systems, as well as Windows. I'm using my Magellan on sgi IRIX right now.
