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?"

    The linked item is not an imager, it's a glorified thermometer. I wish you could get a thermal imager for cheap -- last I checked, they still started in the $3-4K range.

      Because "this building is warmer than the neighbors" doesn't give them probable cause, but "this shape looks like a bank of warming lights" does.

      Besides, they pay of the cost on the first few auto and home seizures.

    The imager police where using was just that - an imager. This is just a cheap infrared thermometer. It's like comparing a motion sensor to a video camera, or your finger to your eyes.

    I literally laughed out loud when this post insinuated that a $150 thermometer was equivalent to a $5000+ vanadium oxide microbolometer.

    Dumb.

      The point is should the cost matter? Someday that vanadium oxide microbolometer may be easier to obtain and be in more general use. Should the availability of the tech matter or should the courts actually use some sort of sound judgement about how intrusive authorities can be? The availability of the technology is not relevant to whether or not the government is stepping on your rights. The technology to break into your house has always been cheap and available yet for some reason surveillance is treated differently.

  3. Not the same. by 0100010001010011 · · Score: 4, Informative

    Thermal cameras used by the cops still cost quite a bit. We had one in the Heat & Mass lab in college and you had to give up your drivers license and student ID to borrow it out, and you couldn't even leave the building.

    The cheap devices on Amazon just look like non-contact temp sensors with some fancy electronics. If someone was trying to snoop around my house with one of the devices you linked to they'd probably be close enough to hit with a baseball bat.

    This is the cheapest I could find however something like this is probably required to do what you're afraid of.

    Still a valid question, but the 'cheap technology' isn't quite there yet.

    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".

  6. Warrantless Police "Observation" ? by bmajik · · Score: 4, Insightful

    If the police are using something stronger than bi-focals to look at your house, they ought to have a warrant. That means they ought to have reasonable suspicion that a _specific_ crime is being committed.

      Mod parent up! All these other posts are acting like having to get a warrant means police can't do it.

      Warrants are routinely obtained for all sorts of things on relatively little evidence. If the police want to spy on someone with thermal cameras, let 'em convince a judge that it's reasonable to think you may be doing something illegal. That's what the warrant process is there for--trying to circumvent it defeats the purpose.

    we have this fancy thermal imager that can see through walls like they arn't there. It detects such subtle changes in temperature you can see the entire inside of the house with excellent clarity from a few hundred feet away. Mind you owning this device is illegal because of the potential for abuse we have exception because it is used for fire dept / search & rescue. But in the wrong hands its a scary device like cops cruising the neighbourhood mind you cops tend to break the law more than your average citizen especially when it comes to traffic violations ( one of our local cops constantly brags about taking 10 min to drive what should be 25 min at the speed limit just to go to the next town for a coffee)

    In plain view means just that, in plain view. Even using your analogy of headlights on a police cruiser, you still can't use headlights to peer into someone's house THROUGH THE WALL or ROOF.

    The spirit of the law is that people have the right to do just about whatever they want in their house, behind closed doors/walls without being subject to a "casual inspection" by the police. Sure, it allows some people to do "bad things" without getting caught sometimes, but more importantly, it keeps the government from being able to micromanage your daily life.

    Sure, because of "global terror" and a bunch of other scary words, people are more readily giving up their personal rights for "safety", but that doesn't automatically make it a good/smart thing.

    Basically, if it isn't grossly obvious that you're doing something illegal, the Police should leave you the hell alone and go find someone who IS breaking the law in public. In my experience, that's not a very difficult thing to find...

  9. A Bright Line is needed by TomRC · · Score: 5, Insightful

    There needs to be a "bright line" on this - that line should be "Any use of sensing devices beyond that of an unaugmented human, constitutes an illegal search."

    That would include remote thermal measuring devices, setting up cameras to watch a house, use of sound amplification, etc.

    For that matter, I would prefer that a warrant be required even to post an officer to watch continuously - i.e. the bright line should be "no more than the equivalent of casual, unaugmented observation". So a police officer could drive by a location, but setting up surveillance would require a warrant. But I don't expect we're likely to see that sort of roll-back of surveillance powers.
