"This case highlights the extreme threats posed to privacy and civil liberties by familial DNA searches and by private, unregulated DNA databases. People should be able to learn about their ancestors and relatives and about possible risks for genetic diseases without fear that their data will be shared with the cops without their consent. However, Usry’s case shows that we can’t count on private companies’ internal policies to keep our private data safe, and we should think twice before sharing our genetic information with a third party."
