Soylent Green was movie from 1973 that predicted the state of the world in 2022. It got a few things right, like people wearing masks. But in this movie the environmental disaster was resulted in the 2022, which makes food very scarce. Consequently a quirky twist has resulted.
The police in Soylent Green wear silver colored helmets and the special star badge on the center of the helmet. The back triangle is black and pointing upwards, while the front triangle is yellow and is pointing downwards.
Upon the yellow badge it is written CITY of NEW YORK POLICE DEPT.
