That's right... He didn't answer the question... You just think he did .
Does anyone believe that was an alert
Whether it was an alert or not, whether you think it was or not, he answered the question. In fact he was so confident of an alert at the time he told them to bag it and tag it. So a trained man is brought in with his trained dogs, the trained dogs do their job, he does his in quite a robust manner and goes home.
This is one of dozens of cases. He's got no vested interest. He hasn't made this whole thing up. An authority such as Mark Harrison, an expert in his field I think we can all agree, deemed Martin Grime and the dogs to be pertinent.
Disparage the evidence and disparage the method as much as you like, but as long as world renowned experts rely on it, and courts accept its veracity, there will be a place. I predict [places index fingers to temples and closes eyes] that these methods will be extended far reachingly (is that even a word?) in crime and other instances.
