Which is why DNA and fingerprint evidence is so valuable as corroborating evidence (person x dna was at the scene and their car was seen at the area), and so hopeless as a dragnet. If everyone in the USA was in a DNA database almost every test would show multiple matches.
Then there is the issue of transference. Person x dna found on housemate y's underwear... rape or shared washing machine?
Fingerprints lack scientific basis for legal certainty More research into validity of fingerprint comparisons needed Date: October 5, 2017 Source: Carnegie Mellon University Summary: A new report on the quality of latent fingerprint analysis says that courtroom testimony and reports stating or even implying that fingerprints collected from a crime scene belong to a single person are indefensible and lack scientific foundation.

Fingerprinting to solve crimes: not as robust as you think

The main problem with fingerprint analysis is one consistent with many other areas of forensic science: subjectivity. Instead of relying on tested scientific methods, the process is mostly based on the subjective beliefs of the analyst... Despite this subjectivity, fingerprint analysts also typically testify in terms of absolute certainty.

Fingerprints: Not a Gold Standard
So to answer your question: Should law enforcement be prohibited from fingerprinting objects found at crime scenes?
You tell me.
