This week I had the privilege of interviewing one of my policing heroes, Ex-Detective Chief Superintendent Hamish Campbell. Hamish spent nearly 40 years in the Met police, most of that time investigating serious crime. He came under intense media scrutiny as the Senior Investigating Officer in the Jill Dando murder enquiry in 1999, which resulted in the conviction of Barry George. George was subsequently cleared of the murder, which today remains unsolved. Hamish reviewed numerous high-profile investigations that resulted in the conviction of some very dangerous offenders, not least Delroy Grant, who was found guilty of dozens of burglaries and rapes of elderly and vulnerable victims.
