You've missed the point again. I've never suggested Grime has tried to coax false positives.. I've said he wants to make sure he doesn't miss anything.. He is therefore getting more false positives.
If MM died elsewhere as I'm fairly sure it will be proved... How do you explain all those false positives for a dog that Grime CLAIMS has such an impressive record.. It simply doesn't add up.
So how does the fact that Eddie alerted after 3 minutes 16 seconds in apt 5a fit in with your theory and Grime stating that he was interested before entering the apt. You believe some of what Grime says ie. Harrisons inventing scent evidence, no inference from alerts but other bits that don't fit into your theories you dismiss out of hand.
I don't need to explain anything, I accept its possible the alerts could be wrong. But you are putting the horse before the cart, when it is proved MM died elsewhere then we can castigate Grime and Eddie.
