Florida cops used "wonder dog" to jail innocent people for a combined 50 years
How many more innocent people were wrongly jailed because of 'wonder dog'? -- OrlandoSentinel.com
[Harass the Wonder Dog] could supposedly do things no other dog could: tracking scents months later and even across water, according to his handler, John Preston.
If it sounds hard to believe, there's a good reason.
After providing prosecutors with testimony for years, Preston was finally discredited by a judge who had the sense to do what others had not: test the dog for himself.
But not until after Preston and his dog had appeared in dozens of cases.
We know that at least three of those cases were overturned — after the defendants collectively spent more than a half-century in prison.
Florida is refusing to look at the other people put away by the cop's (and dog's) testimony, arguing that it's on the convicted who are sitting in prison to petition their cases.
