This worksheet introduces Charles Warren and Sir Robert Anderson, the policemen in charge of the investigation. Students consider a detailed list of the measures that could have been taken and try to deduce which ones were simply not possible at the time; which ones were possible but which were vetoed by the Home Office and why; and which ones were actually taken but why they nevertheless failed. They then have to consider whether Queen Victoria was right to suggest that the police were failing to do all they could to catch the murderer.
