There's a newspaper article that supports, that statement
I'm on a phone at the moment... I'm fairly sure I've quoted it before... It really is quite obvious when you look at the amount of evidence against Gilroy
STATEMENT ON BEHALF OF THE GILROY FAMILY
In response to The Scottish Criminal Cases Review Commission decision to close the case against David Gilroy’s claim he had suffered a miscarriage of justice.
One strand was fully and professionally examined by the SCCRC. They concluded that the evidence given by the dog handler was unreliable. They say that evidence should not have been before the trial court. However, they also say that the absence of the dog evidence would not have changed the guilty verdict. That verdict was by a majority so some jurors did not agree that the case against him had been proved.
http://www.gilroyfamily.info/news.aspThe family argued that without the dog evidence more jurors may have been convinced not to convict ... maybe they were hoping for the infamous Scottish "not proven" ... which some interpret as saying: "We know you did it we just can't prove it".
However the Commission didn't agree with the family's contention and Gilroy's conviction for Suzanne Pilley's murder remains with The Scottish Criminal Cases Review Commission declaring that the evidence given by the dog handler was unreliable.
