Great ideas in Crime Prevention:
When anyone is held up he shall immediately telephone the details to a telephone operator. She wil lplug in every phone in the city and realte the details of the holdup. Near every telephone a shotgun is to be kept hanging on the wall. When the story of the holdup i s spread through the phones every citizen will seize his shotgun and rush to the street. All whistles will blow and at this signal all traffic, including pedestrians, will halt. Anyone besides law officers who moves wil be shot.
