[2] As a young man Kenyon followed in his father's footsteps and worked as a drawer-in at a cotton mill, organising the pattern of threads under the supervision of a "reacher" in the reaching room.
Kenyon was noted for being an effective organiser of crowd control, demonstrating his skills during elections, trades disputes, strikes and Royal visits.
In 1908, Kenyon successfully attained the post of Head Constable of the Penzance Borough Police, succeeding Superintendent Richard Nicholas, who had retired.
The money was stored in the drawer and logged in a book whenever a member of the public handed in found cash to the police station, and had been disappearing ten shillings at a time.
Kenyon noticed that the cash had been signed out by one of his officers, a Police Constable Henry Palmer, with the name and address of the owner of the money entered into the book.
Mr Palmer was questioned as to these discrepancies and admitted he had taken the money, and entered false details into the book, including the forging of signatures.
Based on Palmer's honesty in admitting the crime, and the hardship he had suffered since losing his job, Kenyon pleaded for leniency and suggested he be spared prison and fined instead.
Kenyon remained deeply involved with the police in his retirement, acting as a mentor to the new Chief Constable when there was cause to attend the scene of a fire.
In December 1937, Kenyon encouraged Chief Constable Jenkins to host a charity ball at St John's Hall, the headquarters of the Penzance Borough Police.
