HO45/6647; instructions on the powers of a police constable. The exact powers of a police constable on duty had to be defined, and this document is an early attempt to do it.     Source 2: What is your impression of the powers given to the new London constables- too weak? Too interfering? Easy to follow? What problems would there be in getting new police recruits to stick to these rules? What kind of picture of 19th century London do they give?     Put some of the evidence you have found from these Sources on to your Gallery Worksheet.
