These four photographs from the Scientific Police and Central Service for Signalling and Identification (Scuola Superiore di Polizia e servizio centrale di segnalamento e identificazione) were placed in a comparative quadrant in order to identify possible resemblances between the two bottom photographs.
The Scuola Superiore di Polizia was set up by Salvatore Ottolenghi (1861 – 1934), a disciple of the criminologist Cesare Lombroso. According to the correspondence from 16 June 1932, the Pula Police Bureau in Croatia would have been searching for a man named Giovanni Bibulich, as reproduced in the two top photographs. They asked the Scientific Police in Rome to help in this comparative analysis.
The conclusions drawn are that there are more characteristics of resemblance than disparity between the photographs marked 3 and 1. This may seem extraordinary and unlikely after even just a cursory glance at the two images, however it demonstrates the extent to wchi photography was easily manipulated and used to indict and condemn on spurious bases.
