Does Cheap Tech Undermine Legal Privacy Protections?

bfwebster writes "Orin Kerr, a George Washington University law professor who focuses on legal issues regarding information technology (I own a copy of his book Computer Crime Law) raises an interesting issue about a 2001 Supreme Court decision (Kyllo v. United States) that prohibited police from using a thermal imaging device on a private home without a warrant. (The police were trying to detect excess heat coming from the roof of a garage, as an indication of lamps being used to grow marijuana inside.) The Court made its decision back in 2001 because thermal imaging devices were 'not in general use' and therefore represented a technology that required a warrant. However, Kerr points out that anyone can now buy such thermal imaging devices for $50 to $150 from Amazon, and that they're advertised as a means of detecting thermal leakage from your home. In light of that, Kerr asks, is the Supreme Court's ruling still sound?"

      Yes it is. If there aren't any cheap thermal imagers, the general public doesn't have access to cheap thermal imagers. Therefore, you have a reasonable expectation of privacy from thermal imagers. Once thermal imagers become cheap for mass public consumption, you have two options: you either do nothing, and give up your reasonable expectation of privacy, or put up some sort of thermal barrier so that the public cannot view the contents of your home.

    Does Cheap Tech Undermine Legal Privacy Protections?

    The correct heading would've been: "Does Cheap Tech Ease Police Work?" And the answer is, yes it does. The court didn't declare marijuana-growing legal — it just said, that when the cops need to go out of their way to get information, they need a warrant. Once the devices, that were rare in 2000, become common place enough for each cruiser to have one, the information could be considered "in plain view" and no warrant is needed.

    Even more generally, the cheap tech makes things hitherto impossible or very hard, possible or even easy. If, indeed, the our concerns were really for privacy (rather than for obstructing justice, when it goes after crimes we feel shouldn't be crimes), we should worry about anyone using these and similar devices to, for example, "see through" walls, curtains, or bushes. If you can use them to take a picture of a rabbit in the night, your neighbor — or some "reality show" — can film you rolling in hay...

    Indeed, some time ago Animal Planet was presenting wonderful movies of African fauna. They were shot at night in such darkness, that the cats themselves couldn't see the cameras or each other. But the cameras saw them, and the picture was quite good... Roll forward a few years, and sponsorship by a heavy-weight like Mutual of Omaha will no longer be necessary to obtain such equipment...

    In light of that, Kerr asks, is the Supreme Court's ruling still sound?"

    Anything reasonably available to you should be available to the police. Thermal imaging scanners, however cheap they become, will never be a commonly available item. Therefore, a warrant should be required because what they're looking for is not in plain sight. Think of telescoping lens and using infra-red to see through drapes to spy on people having sex. In this case, though the technology is readily available, the average person wouldn't do this. There is therefore a reasonable expectation of privacy that people aren't doing this for lawful purposes. Having sex in front of the bay windows of your house, during the day, without pulling the drapes back -- a passerby could see that, and therefore the police can bust you for indecent exposure.

    I thought that it was more about the expectation of privacy that people have inside their own homes and not just the ability to peer inside it.

    You thought wrong... If something is "in plain view", then police needs no warrant to follow-up. For an obvious example, if a cop hears a shot inside a house, he needs no warrant to start investigating. Further, if the window/curtains are open and he can see a crime, his observations can (and should!) be used in court.

    Similarly, if we the humans were equipped to detect infra-red light, the police wouldn't have had no problem that's described in the write-up. Arguably, the humans are so equipped now — and that's, what the article is about...

    For example, 100 years ago we didn't really have electric lights and thus could barely see at night — without street lights. So, to notice something in your yard at night back then, the cops needed a warrant (for they had to drag some serious lightning equipment). Today they'll see it in their cruiser's headlights driving by and it is thus "in plain view".

    If I have a briefcase full of documents and leave it on the table in the coffeeshop while I use the bathroom, a police officer is not allowed to open it and look inside without a warrant. Certainly "opening a briefcase" is technology in common use. The Supreme Court's ruling may not be valid, but the 4th amendment still stands. While unavailability of technology may be an additional limitation on government authority, the availability of technology does not grant the government new authority which it does not have under The Constitution.

  14. Supreme Court of Canada's take by SpeedyDX · · Score: 3, Informative

    The Supreme Court of Canada took it in another direction in R. v. Tessling (Wikipedia summary). Basically the SCC asked whether there was a significant privacy interest in images that don't provide any precise information on what's happening inside the home. This speaks to both points. The first is that the SCC determined that those images are not particularly invasive. You can see heat patterns, but no specific activities. The second point here is the emphasis on the subject matter of the image, and not whether the technology to produce that image is widely available.

    Thus with the SCC's stance, it seems that if there exists some technology that can look through the walls of a home and see precise activity, then that technology would at least require a warrant.

    In any event, I don't know if Kyllo's decision was that weak in the first place as to hinge on the question of whether a technology is widely/cheaply available. A much more important aspect of Kyllo seems to be the emphasis put on the "sanctity of the home". If the Court hears a similar case in the future, I'm positive that the sanctity of the home question will play a huge role in the decision.
