Final answer:
There is no specific number of latent fingerprint points that must match the suspect's fingerprint for courts to consider it a positive identification. Courts rely on the judgement of fingerprint experts to determine the strength and reliability of the evidence.
Step-by-step explanation:
In the United States, there is no specific number of latent fingerprint points that must match the suspect's fingerprint for courts to consider it a positive identification. Instead, courts typically rely on the testimony of a fingerprint expert to determine the reliability and strength of the fingerprint evidence.
Fingerprint experts compare the unique ridge patterns and characteristics of a latent print (found at a crime scene) with a known print (such as a suspect's fingerprint). They look for similarities and differences between the two prints, considering factors like the clarity of the print, the number and quality of matching points, and the rarity of the observed characteristics.
While it's important to have a sufficient number of matching points to support a positive identification, it ultimately depends on the judgment of the fingerprint expert and the specific circumstances of the case.
