Graphics Advances Make Identifying Real Images Difficult

destinyland writes "The FBI's geeks admitted they were nervous over computer-generated images at a recent forensics conference. In court they're now arguing that a jury 'can tell' if an image is real or computer-generated — which marks the current boundary between legal and illegal. But reporter Debbie Nathan argues that that distinction is getting fuzzy, and that geeks will inevitably make it obsolete." Note: some of the linked (computer-generated) images may be disturbing.

      Child porn: real or virtual? A day in the burbs and the forensics conference

      (ALL IMAGES IN THIS POST ARE COMPUTER GENERATED)

      To go right to the real or virtual article, skip all the emo in italics. I wont be offended!

      A funny thing happened to me this weekend in Huntington, Long Island. Iâ(TM)d taken a commuter train there from Manhattan, to interview someone in a neighborhood thatâ(TM)s walking distance from the local railroad station. (In case youre wondering why I havent posted lately, Im really busy with other work these days. Why else would I go to Huntington?) So I was hoofing it down New York Avenue when a cabbie screeched up and offered me a ride â" for free. âoeThanks,â I said, leaning into his window. âoeBut why?â âoeBecause you have to pass the day-labor site. Thereâ(TM)s lots of men there from Central America. They yell bad words to women going by.â

      Iâ(TM)m 57 years old and slowly shrinking, maybe, but people seldom mistake me for a shrinking violet. I can deal with a few catcalls and âoeMamiâ(TM)sâ (assuming my wrinkled old self could evoke them in the first place). I tried to elucidate my philosophy to the driver: Itâ(TM)s always worth a few bad words to learn about stuff â" then communicate the stuff to others.

      Well lah-dee-dah, youâ(TM)re probably saying. Nice story, but whatâ(TM)s the point? Especially when the real subject of this post isChild Porn®.

      So hereâ(TM)s the point. Lately, when it comes to writing about child pornography issues, I suspect Iâ(TM)ve caught Huntingtonâ(TM)s Taxi Disease from my colleagues in the journalism biz. I notice that whenever I get an urge to report on the subject, I start worrying that if I publish it, Iâ(TM)ll hear âoebad wordsâ from people from âoeCentral-Weirdo Americaâ â" people who actually like child porn. Iâ(TM)ll have to read their emails (some of which make interesting points about free speech, the fourth amendment, government repression, etc.), then decide whether or not to post them. And if I post, the journos of MSM-villeâ"my colleagues! might look askance. After all, some have already told me that they, themselves, will not write about child pornography for precisely this reason: it freaks them out to get follow-up email from the pedos.

      Iâ(TM)m also afraid my colleagues will tsk-tsk about why I write about this icky subject in the first place. âoeIs she obsessed or something?â they could be thinking. Perhaps they ask why I donâ(TM)t insert boiler plate into the first paragraphs of my articles. Riffs like, âoeOf course, child porn is the most horrible thing in the world, and the people involved deserve strong punishment.â This is supposed to show everyone the writer is a normal person who does not want to hear from pedos. I try to avoid such verbiage because I think itâ(TM)s knee jerk and stupid. Besides, Iâ(TM)m extremely reluctant to close off communication with anyone. I get some of my best tips about the malfunctioning of our various civic institutions from people close to those institutions â" who are often criminals, both apprehended and as yet uncaught. (http://www.imdb.com/title/tt0022100/">M is still one of my favorite movies.)

      I thought the purpose of child-porn laws were to ensure that no children were hurt (a fairly noble goal). Pfft.

      The purpose of child-porn laws is to create fear in parents and then tell them your party will take care of their children and they needn't worry - if only the vote for you. In other words: The purpose of child-porn laws is to generate votes.

      I've yet to see the slightest bit of evidence that any of these laws had any meaningful effect on actual child abuse at all. It's probably because the aim of those laws is the dangerous foreign stranger who abducts and abuses your child (a nightmare for all parents) instead of father/mother/uncle who abuses a kid (the by far most common case in real life).

    The justification for child porn laws is that real children are harmed in making it. The justification for arresting purchasers is that they create the market for it. It doesn't matter whether they buy CG or real porn, they still encourage the crimes against children


    What? That conclusion doesn't follow from the premises you gave.

    The justification for making the production of child porn illegal is that it harms children. The justification for making owning child porn illegal is that it encourages producing child porn (and thus encouraging more harming of children).

    CG child porn doesn't harm children in its production, because its production doesn't actually involve children. And following the analogy, consumption of CG child porn would encourage the production of more child porn, but given the fact that you can produce it without running afoul of the law, you'd get more CG than real child porn produced.

    How does producing images that look like child porn without actually abusing children encourage crimes against children?

    I was in a jury for a case where a guy has child porn that he "made" using legal porn he found online, but photoshopped on the faces of young girls he knew (including a stepdaughter). In Virginia, we found him guilty because he "manufactured child porn", so it was almost as bad as having actual underage girls photographed in those scenes. It was an interesting case because of the legal definitions.

      1) No. In a jury you decide guilt or innocence based on what YOU think is correct. If you disagree with the law, "jury activism" is a legitimate form of protest. Difference being, if you deadlock the jury you can actually do some good.

      2) so what? Prove your stupid assertion. By your logic he already caused "trauma" to those kids the first time he fantasized about them. He had pictures of kids he knew. Unless he was distributing this hackneyed concoction there was no "trauma" involved except the trauma he now faces in prison, convicted of a thought crime.

    "Playing violent video games like Doom, Wolfenstein 3D or Mortal Kombat can increase a person's aggressive thoughts, feelings and behavior both in laboratory settings

    and in actual life, according to two studies... Does that qualify as harm? I would think so. However, since you seem to value my own opinion over that of trained psychologists, I'll answer that question for you with another question. Is the damaged caused by violent video games greater than the harm caused by the gov't stepping in trying to regulate such things? Then ask yourself the same thing about child molestation and child porn. Be sure to recognize that while violent video games are not illegal, child porn is. Also, be sure to consider if your opinion would change if you had been a victim of either crime.

    There are TONS of things that are harmful...and proven harmful to adults, that are perfectly legal. Alcohol and smoking are two great examples. Let's target booze. It is proven to be harmful if abused in humans. It provably DOES change and alter behavior, with many cases linked to violent and/or sexual behavior that is illegal. Yet...do we ban booze? No...we make the person responsible for their actions, whether under the influence or not.

    Same with violent video games and pr0n, (which have much less concrete data behind their influence on behavior than alcohol)...you are responsible for your actions after being exposed to them.

    Bottom line, IMHO, as an adult, you should be allowed to do pretty much what you want UNTIL it violates anothers freedoms or harms them.

    Viewing CGI depictions of crime causes no harm to a victim...whether it be simulated murder, incarceration, or sexually deviant behavior. So, what is the harm? Seems pretty much like playing some video games actually...just more realistic, and some people get their jollies off on it.

    I don't think it is the govt.'s place to tell you as an adult what you can do, use, view or participate in unless it harms another person directly. It is not the place of the govt to protect you from yourself....do what you will, but, face the consequences if you fsck up....THEN the govt steps in.

    The main thing I learned from studying psychology for six years in university is that every study apparently has an agenda, and with all the ones I participated in as a member or a researcher, they are all based on faulty assumptions about how humans work, and how people respond when they know they're being studied.

    The "conclusions" below, are inherently rife with all sorts of debatable points.

    * developed an increased sexual callousness toward women

    Or the kind of people that will get paid/studied to watch hard core porn for weeks are the kind of people that already have sexual callousness.

    What the hell is sexual callousness anyway? I'd argue that it's the default setting for males, who are not mate-for-life animals, despite what the Bride Magazine and the Bible leads us to believe.

    * began to trivialize rape as a criminal offense or no longer considered it a crime at all

    Or were just being more honest about what they actually thought. Few people run around telling everyone they know they trivialize rape, murder or such due to the social consequences. I'm pretty sure I'm not the first person to consider murder as a viable alternative to dealing with customers or employers or family members. In America we trivialize rape, murder, and violence constantly in our culture. Football and UFC are acceptable "alternatives" to violence that we aren't allowing ourselves to do, so we invent a rule-based sport, unless we can make a case for war somewhere on earth, then we do it with a vengence. Rape was never considered a crime in marriage, until very very recently. Women married in their early teens. Hard core porn exists because it's something we cannot acceptably do, though plenty of people want to. Porn doesn't invent the desire. We have the desire so some people like it. We don't like abused children, but B. Spears claimed to be a virgin in a schoolgirl costume and sold a whole lot of albums. I'm sure eveyone watched her videos for the music.

    * developed distorted perceptions about sexuality

    That's agenda all over. What is "distorted"? Anything other than missionary? Bologna. Define normal please.

    * developed an appetite for more deviant, bizarre, or violent types of pornography (normal sex no longer seemed to do the job)

    Normal sex rarely does the job anyway, but I'm a pervert. I'm sure oral sex is deviant and bizarre too (so silly, you'll never make a baby that way). I feel sure that this study should have concluded that wasting time trying to give the girl an orgasm is bizarre and distorted. In my biology classes they stressed that female orgasms are not relevent to procreation. The Bible we're supposed to procreate, not enjoy it, so she doesn't get one. Amen.

    * devalued the importance of monogamy and lacked confidence in marriage as either a viable or lasting institution

    Agenda. Monogamy is an invention from thousands of years ago to protect children and provide for women. It isn't natural at all, for men or women. I base this on the observation that almost everyone has had sex with more than one person (slashdot excepted) and many times cheat on each other. Also, we apparently have divorces from monogamy, when it get's too boring, so we don't take it that seriously.

    * viewed nonmonogamous relationships as normal and natural behaviorxi

    Agenda. That's because it isn't normal behavior. We lust or have sexual thoughts about other people all the time. We may emotionally have strong connections to an individual, but sexually it's normal to think of someone else now and then or appreciate a woman's assets as she walks by.
