 Since the crime of burglary required a jury trial in the Old Bailey, Edward Henry, the Assistant Commissioner (Crime) of the Metropolitan Police Service and head of the Criminal Investigation Department, was determined to make this case succeed.As the man who devised the Henry System of Fingerprint Classification and the founder of the Fingerprint Bureau, he knew that only the soundest sort of Crown prosecutor would be able to convince conservative English judges and a sceptical jury to overcome their prejudices.For these purposes, he decided on Richard Muir, a prosecutor with a reputation for thoroughness and an exacting nature.
