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?
