18 dog teams? What a thorough experiment. Sounds like the infamous chocolate weight loss study that was pushed to the media that made them look stupid.

To a small degree I can agree to this. But I have k9 officer friends and I know their dogs. Good luck with this. It means a bad and impatient handler rather than an ineffective dog. But it's alright, police baaaaad. Evidence is evil.

Dogs are very good at reading people and if the handler wants an indication they will get it; they may not even realise that they're influencing the dogs. As others have said, this has been known for a long, long time. There was even a book written taking a wry look a scent dogs (and the plans for scent bees etc that were in vogue during the great war on terror) [1]. That said, dogs can be fantastic when used for fin…

...and yet dog alerts (encapsulating handler biases) alone are still used to establish probable cause in the US to strip people of their rights to privacy, and has resulted in jail for thousands of people who do not deserve it.

It's better than absolutely no preventative measures at all

Is this not fairly well understood? e.g. https://en.wikipedia.org/wiki/Clever_Hans > Clever Hans (in German: der Kluge Hans) was an Orlov Trotter horse that was claimed to have performed arithmetic and other intellectual tasks. > After a formal investigation in 1907, psychologist Oskar Pfungst demonstrated that the horse was not actually performing these mental tasks, but was watching the reactions of his trainer. He…

Is there any proof that "the trainer was entirely unaware that he was providing such cues." Obviously the trainer has an overwhelming incentive to lie.

That's very debatable. I, personally, would much rather that people in possession of drugs go free rather than the police using the dogs as an excuse to search people they don't like the look of.

What kind if prevention are we talking about? Nitrate-sniffing dogs, or cannabis-sniffing dogs?

Yes, but I suspect you would also support lighter sentencing or even decriminalization of drugs. I don't think you'd think the same if it was concerned potential terrorists or child sexual abusers.

Basically, this kind of comment usually encodes some belief on what the law should be rather than a belief about how it should be enforced. And that's just not the issue at hand here.

In this context it is ridiculous that a dog test is considered a probable cause for a police search: news.ycombinator.com/item?id=10942196

Is it really? Probable cause doesn't need to be a high bar, in my opinion. Contrary to what people here seem to think, I don't think a police search is that invasive and I'd rather we perhaps search some people on shaky grounds than we let people with drugs/bombs/whatever walk free.

So you're cool with a cop that is biased against black people using their dog as a pretense to search them? Oh, and, yes, a police search is invasive and demeaning. I suggest you try it before you discount it.

Then just do away with 4th amendment, rather than pretending that cops respect it.
