Explosive Detecting Devices Face Off With Bomb Dogs
First time accepted submitter titan1070 writes "French scientist Dr. Spitzer and his colleagues have been working on a device that can sense faint traces of TNT and other explosives being smuggled into airports and other transportation methods. the hope for this device is that it will surpass the best bomb finder in the business, the sniffer dog. From the article: ' While researchers like Dr. Spitzer are making progress — and there are some vapor detectors on the market — when it comes to sensitivity and selectivity, dogs still reign supreme.
“Dogs are awesome,” said Aimee Rose, a product sales director at the sensor manufacturer Flir Systems, which markets a line of explosives detectors called Fido. “They have by far the most developed ability to detect concealed threats,” she said.
But dogs get distracted, cannot work around the clock and require expensive training and handling, Dr. Rose said, so there is a need for instruments.'"
That statement, entirely by itself, should qualify dogs as a better option, but let me elaborate...
so do employees. What's your point?
Dogs work. They work well. They are unsurpassed in reliability by any instrument we've been able to devise.... the fact that they can't be used like machines could should no more be a reason to not use them than the fact that humans can't work like machines should be a reason to not employ people.
When a machine can do a *BETTER* job at it than a dog... then I could see replacing them being viable. Until then, however, let Spot and Fido keep their jobs.

"We can't use dogs to spy on everybody, everyplace, all the time."
You wouldn't want to anyway. In blind studies, drug- and explosive-sniffing dogs actually have a pretty terrible track record. A literally unacceptable percentage of false positives, for example. Turned out, the dogs were responding to very subtle cues from their handlers, rather than their own senses. Which renders them completely inappropriate for law-enforcement use.
Not to mention the probable fact that the dogs are most likely smarter than the average TSA employee.
Have any lawyers won with the argument that the dogs were taking cues from their handlers yet?
Understanding the scope of the problem is the first step on the path to true panic.
"Please link to proof of your "literally unacceptable percentage of false positives" for properly trained canines and handlers."
Easily done.
It amazes me how many people are so ready to call "bullshit" without taking 10 goddamned seconds on Google to check their facts.
If you think that is the only such study, you are mistaken. Google it dude. Learn something.
Here's another. Though not an independent study, it did evaluate actual success rates according to the courts' own records and found only a 44% success rate. And that was the average. For one minority, the true-positive rate was clear down at 27%. (Can you say "cues from handlers"? Sure. I knew you could.)
Also, they are probably not the best things we have. And even if they were, that "best" is pretty obviously not good enough.
You can't just argue that it's "the best". It has to be good enough. Not only that, but the huge potential for intentional cuing of the animals is seldom considered.
