Iain McKie was a police officer for thirty years, rising to the rank of Superintendent. He has spent the last ten years fighting the Police, the Scottish Criminal Records Office and the Scottish Executive after experts wrongly identified his daughter's fingerprint at a murder scene. He has researched fingerprinting extensively, spoken at forensic conferences in the UK, Canada and America and is recognised as a campaigner who has not only secured justice for his family but has also brought about major changes in the forensic services in Scotland and in fingerprinting world wide. Married with seven children, he now lives in Ayr. Michael Russell is a well-known author and commentator who was an MSP for the South of Scotland from 1999 to 2003. He met Iain and Shirley McKie in February 2000, was convinced by them, and agreed to take on Shirley's case as a parliamentarian. He has championed it in politics and the media ever since. He lives in Argyll.
