For someone who claims to hate witch hunting, intution and mental illness, it's hilarious you don't believe in scientific method and proof, that is DNA testing, footprint analysis, luminol, pathology, etc. It reminds me of the cadaver dogs in Portugal in the McCann case who sniffed out a cadaver in eleven different places and yet people think the dog is somehow mistaken, and people the world over should continue looking for 'sightings' of Maddie.
Wake up, smell the coffee. Science doesn't lie. Cadaver dogs are not 'mistaken'.
Science doesn't lie. But results are only as good as those who collect, analyze, and interpret the data and/or samples. The collection of the DNA samples was not done according to protocol unless one thinks using visibly dirty gloves and not changing gloves between handling evidence is correct. If one thinks that not changing shoe coverings between rooms is correct protocol, Stefanoni's team was great. If one thinks that storing evidence in a shoe box or wrapping it in gift wrap from the murder scene is correct protocol, then Stefanoni again was great.
I don't know about cadaver dogs' accuracy but drug sniffing dogs are not 100% accurate. In fact, just like luminol, dogs often give false positives.
"In 2010, a team of researchers at the University of California, Davis set out to test the reliability of drug- and bomb-sniffing dogs.
The team assembled 18 police dogs and their handlers and gave them a routine task: go through a room and sniff out the drugs and explosives.
But there was a twist. The room was clean. No drugs, no explosives.
In order to pass the test, the handlers and their dogs had to go through the room and detect nothing.
But of 144 runs, that happened only 21 times, for a failure rate of 85 percent."

Although drug-sniffing dogs are supposed to find drugs on their own, the researchers concluded that they were influenced by their handlers, and that's what led to such a high failure rate.
"Dog handlers can accidentally cue alerts from their dogs by leading them too slowly or too many times around a vehicle, said Lawrence Myers, an Auburn University professor who studies detector dogs. Myers pointed to the "Clever Hans" phenomenon in the early 1900s, named after a horse whose owner claimed the animal could read and do math before a psychologist determined the horse was actually responding to his master's unwitting cues.
Training is the key to eliminating accidental cues and false alerts, said Paul Waggoner of Auburn's detector-dog research program.
"Is there a potential for handlers to cue these dogs to alert?" he asked. "The answer is a big, resounding yes."

I like my coffee black if you're making it.
