Well, if that ain't a great way to manufacture a warrant.

What exactly is wrong with cadaver dogs, anyway? I'm guessing it's that cadaver dogs actually work on scientific principles. (Edit: dogs also can't smell a body from across the street. At least, I don't think they can.)

[dTal]

Cadaver dogs were used to locate the remains of murdered journalist Kim Wall, which were in plastic bags at the bottom of Køge Bay. I'm pretty sure smelling a body across the street wouldn't present a challenge. Dog noses are insane.

[Enginerrrd]

Smells like parallel construction to me...

Dog noses ARE insane, but they're probably not THAT insane.

[dTal]

Your skepticism is unwarranted - it's real. There's a documentary about it. Small droplets of rotting fat float up to the surface, where the dog can smell it. They had to account for ocean currents and the rate at which the bubbles rise in order to sufficiently narrow the search area. They couldn't find it at first, because they misunderstood the mechanism and assumed it was gas bubbles, which obviously rise at a different rate.

Besides - where else would they have gotten the information from? She was killed on a submarine with no one else aboard but her murderer, and he wasn't talking.

[davidwritesbugs]

So dumping my bodies at sea is not safe? This is surprising bad news, thanks Season 1 Dexter.

[addingnumbers]

You must have stopped at Season 1, season 2 started with all those bodies found in the first episode.

[coffeefirst]

They've been using dogs to test COVID samples, and discovered they're more accurate than the chemical tests.

My beagle once lead me through a park about 80 feet to a dropped slice of pizza.

So, yeah, given a body is going to be a massive horrible smell that's a lot easier to find than cold pizza, this is entirely plausible.

[Arrath]

That dog was on a mission, what a good pup!

[quxpar]

Dogs smell in stereo with detailed temporal information. They know which way a deer passed and how many days ago.

[sumthinprofound]

Dogs' sense of smell is sufficent to detect a teaspoon of sugar added to an Olymic size swimming pool.

[pmarreck]

I just learned of this case. Wow. Wait, wasn't she inside a sub which he ditched?

[dTal]

She wasn't inside at the time; as stated, she was in several plastic bags at the bottom of Køge Bay.

[lupire]

Alert dogs respond to handler signals and are used to fabricate probable cause, much like witching.

[Cthulhu_]

There should be a discouraging compensation paid to the suspect if their property is searched and nothing found. An "apologies for your trouble / time", and of course a hearty compensation for any damage done.

[AlexandrB]

Paid by whom? In cases of police getting sued after a wrongful death, the municipality typically pays the bill. The police budget is unaffected. In such a system there's little incentive for police departments to be careful with which property they search, even if the owner is compensated.

[MPSimmons]

>The police budget is unaffected

I would have to imagine that after several such incidents, the police budget would begin to be affected.

[SamoyedFurFluff]

What happens if it becomes a “the body must’ve been here at some point and then moved”? For example cadaver dogs have been used on cars, houses, etc. with clearly no body precisely to put under suspicion that a body was under temporary storage.

[0des]

That would be gamed in a heartbeat.

[LanceH]

It could only be gamed if dogs aren't accurately finding bodies.

[SamoyedFurFluff]

Dogs aren’t accurately finding bodies and are often deployed even when cops know no body is present (such as a car). Now what?

[LanceH]

Exactly. Someone suggested we compensate people who are searched when nothing is found. The next person says that would immediately be gamed. I'm saying it would only be gamed if dog searches don't work.

Personally, I would like to see some sort of registration before an animal or device is used for a search. A search would be invalid unless it is applied for. Then the results must be entered upon completion (or assumed to be a failed search). Then we could see the results and how accurate these animals or "scientific" tests are in practice.

Instead we have warrants essentially backed by dogs who have no track record. The police are allowed to say, "the dog alerted, so drugs must have been present at some point and must have been moved." This has even led to further searches for where the drugs were moved to. All without anyone knowing the actual accuracy or effectiveness of a dog's search ability -- only that it was "certified".

[0des]

Were you born after the 9/11 attacks?

[thesuitonym]

Maybe cops shouldn't be doing that.

[hacktavist24]

True, and that is a problem if peoples' properties get dug up, as a sibling comment notes. But, in contrast to drug dogs, where an alert creates probable cause for a search where things other than drugs can frequently be found, cadaver dogs typically either find remains or not. There generally isn't much else one can find digging around in the dirt that's incriminating, so, from a legal/justice POV, the harm of a false alert from a cadaver dog is much less than that from a false alert from a drug dog.

[SamoyedFurFluff]

I heavily disagree with this notion. Cadaver dogs falsely alerting can tip police into arresting a suspect and bringing them in for questioning (this can often be newsworthy and cause one’s neighbors, community, the internet, and employment to also treat the person with suspicion or assume guilt) , or focusing on a suspect while not chasing other leads for an actual killer, or be used as circumstantial evidences at a trial even when no body is found. There have been cases where the cadaver dog alerts around a car, with clearly no body to be found, and this is used as circumstantial evidence that the car must’ve been used to carry a body.

[lnxg33k1]

This is one of the thoughts every now and then makes me happy to don't live in a society affine to the US culture, and sometimes I can't understand how people can't see how this messes everything up, this attitude of terminating the life of those who have just been suspected, by giving for granted that everyone is already guilty before the trial even starts is crazy, and makes the whole country more blackmailable, I can't imagine the amount of people who gave up to blackmail just because otherwise their life would be trashed

But to get back on point, what should the police do? They have an investigation to do and the dog trying to say something? Should we avoid questioning people just because society is fucked up?

[throwaway0a5e]

Assuming people are guilty on mere suspicion isn't a US thing. It's a rich suburbanites who are never subjected to baseless fishing thing.

[lnxg33k1]

More than rich I would say it’s an evangelical / Protestant trait, somehow. I’ve experienced it in London, and Amsterdam that are anyway still evangelical, but absolutely not in Spain or Italy that are catholic

I’m not sure I’m not a religious scholar not believer but have still received a catholic education being Italian (went to catholic private schools) and a lot of things that I absolutely hate are mostly explained by people I talk to with being a result of evangelical education

What do you think? Might it be more cultural than related to status?

[m-watson]

Worth a read through just to see some examples of cadaver dogs being problematic.

https://www.science.org/content/article/should-dog-s-sniff-b...

[deschutes]

It's amazing that a dog smelling odors could be evidence of anything, even taken in the context of other evidence. In my view the dog is simply a tool to find evidence. The tool indicating there is evidence is not evidence.

[MPSimmons]

That's kind of the problem. If the dog indicates there's evidence in a place you can't get to (private property, for instance), the dog's indications can be used as evidence to get a warrant.

What is their false positive and false negative rates?
