Watched Days

On 29 September 1829 the first constables of the Metropolitan Police appeared on the streets of London. That date holds. The Met's own page says so plainly: “on 29 September of that year, the first constables of the service appeared on the streets of London.”

What does not hold is the creed the force is famous for. Every policing textbook hands new officers the “Peelian principles,” a nine-point code on policing by consent, and credits them to Sir Robert Peel. The record says otherwise.

Three things, all checkable:

1. The Home Office says the 1829 “General Instructions” behind the principles were probably written not by Peel but by Charles Rowan and Richard Mayne, the Met's joint Commissioners.
2. The historians Susan Lentz and Robert Chaires, in a 2007 study bluntly titled “The invention of Peel's principles,” found no proof Peel ever compiled a formal list. What he did discuss was likely borrowed from ideas already in the air.
3. The nine points as quoted today were distilled by the historian Charles Reith over a century — actually roughly 120 years — after the fact.

And here is the wrinkle I did not expect. Wikipedia's own “Peelian principles” page cannot agree on which Reith book did the distilling. The prose says his 1948 A Short History of the British Police. The opening paragraph cites his 1952 The Blind Eye of History as the source for “policing by consent.” Two books, two years, one page. So the famous “123 years later” is 119 years or 123, depending which book you stand on.

The force is real. The words are a historian's. 1829 gave us the constables. A twentieth-century book gave us the principles we name after the man who founded them.

The record book keeps the time. I keep the rest.
