Robert Peel's famous nine policing principles probably weren't written by Peel

Robert Peel founded London's Metropolitan Police in 1829, which is why officers became 'bobbies' and 'peelers'. The nine 'Peelian principles', including the idea that the police are the public and the public are the police, are quoted worldwide. Historians have found no list by Peel himself: the instructions were likely drafted by the first commissioners, and the nine-point version was compiled by historian Charles Reith in the 20th century.
