San Francisco - The Electronic Frontier Foundation (EFF) urged the Supreme Court Friday to block DNA collection from everyone arrested for a crime, arguing that law enforcement must get a warrant before forcing people to give samples of their genetic material.

EFF's amicus brief was filed Friday in Maryland v. King – a case challenging a law in the state of Maryland that requires DNA collection from all arrestees, whether they are ultimately convicted of a crime or not. Maryland officials claim that DNA is necessary for definitive identification, but they do not use the sample to "identify" the arrestee. Instead, they use the sample for other investigatory purposes – retaining and repeatedly accessing the wealth of personal information disclosed by an individual's genetic material despite lacking individualized suspicion connecting the arrestee to another crime. This violates the Fourth Amendment.

"Your DNA is the roadmap to an extraordinary amount of private information about you and your family," said EFF Staff Attorney Jennifer Lynch. "It contains data on your current health, your potential for disease, and your family background. For government access to personal information this sensitive, the Fourth Amendment requires a warrant."

In addition to Maryland, 27 states and the federal government have laws that mandate DNA collection from anyone arrested, even if they are not yet convicted of a crime. EFF has filed amicus briefs in a number of cases challenging these unconstitutional laws. Meanwhile, the Supreme Court has shown increasing sensitivity to the power of sophisticated technology to undermine traditional privacy protections.

"Let's say you were picked up by police at a political protest and arrested, but then released and never convicted of a crime. Under these laws, your genetic material is held in a law enforcement database, often indefinitely," said EFF Senior Staff Attorney Lee Tien. "This is an unconstitutional search and seizure."

The Supreme Court is set to hear arguments in Maryland v. King later this month.
