The circulation of the technical knowledge of the scientific police is an example of the technological transfer between the two sides of the Atlantic, and of the existing tensions in the field of positivist criminology. The important body of letters received by Juan Vucetich (La Plata, Museo Policial) from European correspondents is an eloquent demonstration of this. His personal identification system, which replaced Bertillon’s anthropometric measurements with the collection of fingerprints, was adopted by the Italian forensic police after it spread to Latin America. In this process, what was weakened was the anthropological perspective of Lombrosian criminology, with its baggage of signs of degeneration and atavism, while a new perspective of institutionalization of scientific knowledge by the state was opening up.
