Shirley McKie is a former Scottish police officer who was accused of leaving her thumb print on the bathroom door frame of a murder crime-scene in Kilmarnock. She denied she had ever been in the house. Mckie was charged with perjury but was acquitted. The sole evidence against her was the mismatched thumbprint. A scandal subsequently developed because of allegations of misconduct on the part of the SCRO and the police.
I was expert adviser to the Scottish Parliamentary Inquiry Into the McKie case.
