The forensic technique that was introduced to the United States by Scotland yard in 1904 was Fingerprinting marching.
EXPLANATION:
A fingerprint is an 'impression left' by the 'friction ridges of a human finger'. Fingerprint of each human is unique and remains unaltered throughout the lifetime.
Because of these reasons, fingerprint is used as a reliable means of classifying and identifying the human beings.
With the development of fingerprint reading technology, many prisons began to use fingerprints as a 'means of identification'.
The U.S. military began to 'adopt the use of fingerprints'. Soon thereafter, police agencies also began to adopt the 'use of fingerprints'.
