because you have suspects and they take their finger print and it is probley one of them
How do you mean... within our legal system, never. If on a surface, then it would depend on the environment.

Automated Fingerprints Identification System
If a crime is committed, and fingerprints are part of the evidence gathered by the forensics team in a police department, they are first run through their database to see if they match anybody already in the system. If not, then these services take prints of suspects and attempt to match them to those from the crime scene
Fingerprints were used for the first time in 1901. Scotland Yard started using the Henry Classification System, invented by Sir Edward Richard Henry. Five years later, in 1906 the New York City Police Department became the first in The United States to use fingerprinting.
Latent fingerprint examiners are people who look at fingerprints left on a crime scene. Also register, search, analyze, and identify fingerprints in the Automated Fingerprint Identification System (AFIS). They also record criminal history and provides expert witness testimonies in court. They view animated or hard copies of fingerprints and they also prepare the print for computer entry. They also enhance the fingerprint with the computer. They also have to prepare displays of the latent fingerprint for testimonies.
"An Englishman, Sir Edward Henry, who had been given tuition in fingerprints by Galton, devised a workable classification system independently of Vucetich and implemented it in India in 1897. Henry published his book Classification and Uses of Fingerprints in 1900. In 1901, Henry was appointed Assistant Commissioner of Police at New Scotland Yard and began to introduce his fingerprint system into that institution. By the end of that year, the Fingerprint Office at New Scotland Yard was fully functional, the first British court conviction by fingerprints being obtained in 1902. Approximately 10 years after the publication of Henry's book, his classification system was being used by police forces and prison authorities throughout the English-speaking world."
The police officers have a computer system in their car to do that. The computer allows them to access the database to see people's license plate number.
Sir Francis Galton, a British scientist, was the first person to devise a system of classifying fingerprints in the late 19th century. He created a method for categorizing fingerprints based on their patterns and characteristics, laying the foundation for modern fingerprint identification techniques.
When taking fingerprints there must be a fingerprint in the system already. When removing fingerprints from items the item can be placed in a vacuum sealed case where superglue is heated and turned into a vapor where it will attach itself to the item, revealing the prints. The powder clings to the oils and alleles left behind from the fingertips. The fingerprints are then put into the system and the closest matches are found.
