Scientists who specialize in genetics have called the purging of evidence after the DNA revolution disturbing.

"By 1990 to 1993, at that point, DNA is well-known," said Alec Jeffries, the British geneticist who discovered the DNA "fingerprint" in 1984. "They would have known the real utility (of DNA)," he said, referring to most law-enforcement officials nationwide.

Even if statutes of limitations have expired on cases, the samples can still be used to aid criminal investigations into serial offenders. They also can help defense attorneys prove the innocence of their convicted clients when DNA analysis wasn't previously available.
