You have failed to show that Martin Grime said that the dog alerts were unreliable and that the alerts were actually unreliable in themselves. Just because they weren't admissible in court doesn't make them unreliable.
We don't need to know the details of Stockham's tests all we need to know is what job he did and that he was considered an expert witness at the D'Andre Lane trial.
Do we have all the full details of how the drug tests were carried out on the twins and Kate no we don't, yet you accept the result of them.
An expert witness in Britain is expected to be neutral but in America it is big business the rates for which I have heard are very lucrative.
There are also ethical problems arising from their use in america. On a forum like ours we must be aware of exactly what we are discussing and to bear in mind that to us an expert witness is something entirely different from the American model.

The measures included placing experts under the complete control of the court, requiring a single expert in many cases and encouraging cooperation among experts when the parties retain more than one. Experts are required to sign a statement saying their duty is to the court and not to the party paying their bills.There are no signs of similar changes in the United States. “The American tendency is strictly the party-appointed expert,” said James Maxeiner, a professor of comparative law at the University of Baltimore. “There is this proprietary interest lawyers here have over lawsuits.”
American lawyers often interview many potential expert witnesses in search of ones who will bolster their case and then work closely with them in framing their testimony to be accessible and helpful. At a minimum, the process results in carefully tailored testimony. Some critics say it can also produce bias and ethical compromises.
“To put it bluntly, in many professions, service as an expert witness is not considered honest work,” Samuel R. Gross, a law professor at the University of Michigan, wrote in the Wisconsin Law Review. “The contempt of lawyers and judges for experts is famous. They regularly describe expert witnesses as prostitutes.”
