MEPO 2/9953, Daily Sketch article (2nd December 1963). Radios were used by police from 1910, but the miniaturisation of two-way radios made a huge difference to the isolation of the police constable on the street, as this newspaper article from 1963 shows.     These sources are all quite easy to understand. As you look at them, think about: which aspect of police work will be changed? Is this technology an entirely new approach, or a new way of doing an old job? There is some evidence, too, of the attitudes of: the police (Source 2), criminals (Source 3) and the public (Source 4) to these changes.     Put some of the evidence you have found in these Sources into your Gallery Worksheet.
