“DNA databases are increasingly being used for more than individual identification. Searching for partial matches can find that a suspect is likely to be the family member of someone in the database. This brings extended families, including many people who have never broken the law in their lives, under direct police surveillance. And the intrusion of privacy represented by being forced to surrender DNA to a police database is high. DNA is qualitatively different from a fingerprint; it holds extremely personal information about lineage, propensity for disease, and countless other traits.”
