Factual error: There are a number of historical inaccuracies with the police uniforms used. The film is set in 1880, but the Duty Armlets with the alternating short blue/white vertical stripes were not introduced until 1886 (in 1880 they would have had three horizontal white stripes separated by two narrower blue stripes). Whistles are shown being carried, but they were not introduced until 1885 (they used rattles before then). The helmet plates have a generic VR on them when they should repeat the officer's collar number (eg P 129 in the case of Constable Flood).
