MEPO 2/67; this is a letter from a member of the public about the behaviour of the police at a demonstration in Victoria Park, east London, in June 1848.     In these sources, look for: what complaint, or praise, is being given? How do you think the police behaved? What clues can you find as to how the public felt about the police? How did complaints and attitudes change as time went on?     Put some of the evidence you have found from these Sources on to your Gallery Worksheet.
