    If you think about it a while you can see the problem - these stars are in orbit, so they should fall at all. Essentially, the stars are being sorted by mass when they should be just going around in circles...


    Well, that's the obvious expectation if you consider only the interactions between each orbiting star and the center of mass of the galaxy; but their actual motion is a lot more complicated because the you've really got a bunch of non-uniformly distributed objects attracting each other, which is why (besides this effect), you get spiral arms, which aren't clumps of stars orbitting together, but, IIRC, compression waves that move at speeds different than those of the individual stars, with stars bunching up in them and then spreading out after they pass.

    It does not *beg* the question, it *raises* the question.

    And no I won't accept 'modern' usage, dammit I want it to mean what it originally meant.


    The usage "begs the question" without modification, or the more rarelyheard "begs the question at issue", clearly and unambiguously refers to the petitio principii fallacy. The common modern usage "begs the question $foo" is distinct, and refers to calling for another question to be answered. There is no ambiguity (its possible to specify the question at issue when referring to the petitio principii fallacy, but as a argument that demands an answer to the same question originally at issue is precisely the petitio principii fallacy, there is no possibility for confusion even there.)

    It seems to me to be especially pointless pseudo-pedantry to complain about the "modern" usage here, since, in the only case where one might use the construction in the original sense but in the modern usage's structure (so that, if they meaning was different, the usage would be ambiguous), the meaning is exactly identical in either usage.

    Yup, if it doesn't identify that as a licensing term rather than a practical requirement.

    If I buy a piece of software that says on the package it requires a particular operating system and processor, and run it on a different OS and processor and get it to work, I'm not breaking the license, (OTOH, if it doesn't work, I'll have even less ability to take the vendor or manufacturer to court for a refund then I would normally, though all the usual disclaimers of warranty, etc., do as much as legally possible to avoid that even if I use it with a system with the published specs.)

    So, yes, I'd say its a post-sale condition if it is indentified as a licensing requirement up front, since there is a substantial difference between a claim about where the product works, and a binding covenant not to attempt to use the product on any but specified computers.

    You know, if I had any reason to respect your opinion, I might care what you think. But, really, you spew a bunch of stuff that is wrong on the facts, an insane distortion of the holding in a court decision, and then start with personal attacks. Who cares.

    Cowards like you who are willing to give up privacy and rights in exchange for the hope that those they give it to will do the right thing, with no oversight are a sad combination of cowardice and stupidity.


    What rights? There is no "right" to keep secret what is done in public places. And what is done in public places is not within the scope of any reasonable definition of "privacy", either.

    And, even though there is no "right" or "privacy" involved, I still don't think the police should have "no oversight" if they get this technology, or if they don't. If it becomes commercially available, communities should demand oversight as they should demand public oversight of all aspects of police operations, should establish appropriate proceduers with accountability, etc. All I say is that the technology has obvious potential utility and should not be rejected out of hand. All this "no oversight" stuff is stuff you made up to justify attacks based on your own preconceived notions.

    Perhaps you should look in the mirror before you call anyone an "idiot".

    You hope this won't be abused and will make you safer, despite the fact that it has not done so in the past.


    Since this technology has not been used in the past, I fail to see how it could have done anything in the past, or how the failure of technology that has not previously existed to have been effective when it did not exist is any basis for evaluating how effective it might be were it to exist.

    But, no, I don't blindly hope any of that, any more than I hope the same thing about existing police technology like firearms, pepper spray, or automobiles: they all can and have been abused, and they all need appropriate procedures, accountability, and oversight to prevent abuse.

    At the same time, its a good idea that police have access to them.

    The same seems true of this kind of technology to use cameras to provide automated flagging of behavior of potential law-enforcement interest.

    This wouldn't give police any more legal authority to search what is private. It wouldn't give them the authority to arrest without probable cause. It would allow them to behavior in which there is no legitimate expectation of privacy, in public areas, more economically, with automated assistance in detecting behavior which might warrant further attention. They'd still need probable cause to arrest, to search, etc.

    If you replace "won't", with "may not", replace "statistically are unlikely to be able to protect me", with "will be statistically more likely to be able to protect me if granted the new technology", replace "power" with "technology (with no expansion in authority)", and replace "that power is highly unlikely...and democracy in general" with "that power is certain to add to their capability if intelligently applied, and poses little danger to any cognizable privacy interest and absolutely none to democracy in general", then, yes, that's about what I've been saying.

    Why is it that so many people are now willing to hand more power to the central government under the idea that it will make them "safer."
    I'm paying the police to do a job. If there is modern technology that, with no expansion in what is legally permitted for the police to observe or act on, will make them more effective in doing that job, I want them, in general, to have it. I mean, I suppose we could prohibit police from having automobiles and semi-automatic firearms and pepper spray and bullet proof vests and handcuffs and radios, since all of those things gave them, in a sense, more "power" than they once had.

    They are, in the same sense, not responsible for investigating and gathering evidence for a crime: just as you can't sue the police for not preventing a crime, similarly you can't sue them for not investigating a crime against you thoroughly (or at all).

    Read Warren Vs. District of Columbia.


    I'm familiar with the case; it is one of many cases holding that the police of no legally enforceable specific duty to members of the public, as such, in their law enforcement, and this reasoning has been repeatedly applied equally well to what you claim is the "job" of police (investigation and evidence gathering in resposne to crime) as for what you claim is not (prevention of crime). See, for instance, Nichols v. District of Columbia, decided by the US Court of Appeals for the District of Columbia in a consolidated decision with Warren v. District of Columbia.

    Um, no. Radar speed verification is not a search, you don't have a 4th Amendment privacy expectation in the speed of your vehicle on a public street.

    They cannot just radar all cars going by because it is considered a search without probable cause.


    Yes, they can (under the federal Constitution, at any rate; of course, your state may have more restrictive laws of its own.) Probable cause is needed for a search or an arrest, it is not needed to use radar to verify the speed of a vehicle.

    Some people will commit some crimes regardless of the consequences. Some people who might commit crimes in some circumstances will not in others because of the perceived threat of detection.

    The only way you will ever prevent that is to change the social situation of the people committing the crimes.


    Sure. One way to do that is to increase the probability that people who commit crimes against them will be caught. This decreases the feeling that the law is useless and irrelevant to them, and the motivation to seek redress outside of the legal system.
