Martin Grime said he's never gave a false alert. He should know. Look at Morse record that was released. Mark Harrison recommended the best dogs to the PJ.
The dogs' CV is impressive. Besides collaborating in hundreds of investigations, they passed the practical tests brilliantly at the FBI's "Body Farm," the only place in the world where human cadavers are used to simulate homicide scenarios and concealment of bodies. (TOTL)
What is your opinion on Keela PF - regarding the following? She did not alert to the white curtains on her first 'search' but then did alert to them on her second 'search.
Was she wrong the first day and right on the second day? or
Was she right the first day and wrong on the second day?
Either she failed to detect an odour that was present on the first search - or she was correct and no odour was present - which means she gave a false alert on the 2nd search. As forensic tests found no trace of blood - then IMO that is suggestive of a false alert.
