This is on WinXP, WinME, and Win98. I know this because I did the packet trace & analysis of what happened when he booted the machine. When he switched to my local nameserver running on my laptop, mind you, he got spared.

    I would not be surprised if we found a virus that searches through the local (and even LAN-accessible) documents for interesting keywords or types of information, then somehow manages to send this information back to some spying agency. In fact, I think this has probably already been done.

    • economic espionage
    • blackmail (emails showing that he has a mistress / has taken illegal bribes...)

Onion peel routing and distribution through Usenet or WWW bulletin boards could do the rest - untracable information.

    This case sounds interesting for a couple of reasons. The defendent's entire case is out the window, of course, if the prosecution shows that the virus was not responsible for downloading kiddie pr0n. Assume such a virus existed for the sake of argument.

    First, there is negligence for allowing one's computer to become infected. A related precedent would be the owner of a condemned house allowing it to become a crack house. IANAL, but in a lot of ways it seems the cases are similar. One could claim that the software manufacturer (MS) was responsible for faulty software, or that the virus writer was responsible for letting loose his creation. In the same way, the crackhouse owner could claim that the lock manufacturer did a poor job, or that the addicts breaking into his house were at fault.

    Second, if computers become more like personal extensions of ourselves, indispensible, parts of our consciousness in some far-fetched way, then the defendent might take the insanity route. That is, "God told me to take 7 wives and this girl is one of them." However, computers are subject to more detailed forensics that people's brains, so claiming an insane computer might not withstand much scrutiny in court.

    So, the day has come at last. I must say I'm surprised, as I've been expecting it for over 5 years.

    The point is that the law has to decide how much responsibility a person has for what their computer decides to do.

    Up till now, the assumption has been that whatever your computer does, is done at your request, and you are wholly responsible. This despite the fact that that has never been true, and is getting further from the truth every year.

    There is no legal tradition to apply here. The nearest analogy to the relationship between a person and his computer is the relationship between a man and his dog.

    People have kept dogs for thousands -- most likely tens of thousands -- of years, so everyone has a rough idea what the deal is. The general legal view is that you have a duty to keep your dog from causing harm under forseeable circumstances, but there is a distinction between what your dog does and what you do. If your dog attacks a child, you are not guilty of Grievous Bodily Harm, but you might be guilty of keeping a dangerous dog. If your dog craps on the street, that is different than if you crap on the street, but you might still be fined.

    If you are found guilty of not properly controlling a dog, you can be banned from keeping one. If your dog causes harm and is considered not to be controllable, the court can order it to be destroyed.

    (If you deliberately cause your dog to kill someone, that is still murder of course, but your intention is crucial)

    UK law regarding child pornography is so broken as to be seriously unfunny. The police are currently interpreting the law in such a way that if the police can find five images of child pornography on your hard drive, by any means, then you are guilty. Almost uniquely in non-negligence law there is no need to prove intent. As a result it is an easy means for them to get their statistics up so it is zealously persued.

    Now consider the "by any means" bit. As far as I can tell they do a block-by-block analysis of the hard drive. So deleted files, swap and linked files are all identified. So if you use your web browser to read your email and you are sent an email with five indecent images then you're toast. Deleting the mail message doesn't help because the downloaded images still live in your cache. Purging your cache or letting it time out doesn't help unless the blocks get overwritten by other data. If you try to explain this to the police man/woman you will be told that your questioner doesn't use the net so they can't understand what you're talking about.

Unfortunately a filing error thanks to his initial elected representation fucked up everything. They files a day late. Too bad, so sad. In the end he was put to death. The experts that tried to save him are still fighting however. They are trying to get the initial semen samples analyzed by today's DNA technology which lays what they could do in 1990 in the shade. The state where he was convicted and put to death is fighting it though. They are afraid of the truth in essence. If they had nothing to hide than the DNA test would vindicate them if true.
