Maryland v. King
In a 5-4 opinion authored by Justice Kennedy, the Supreme Court ruled that suspicionless collection of the DNA of those arrested for a serious crime did not violate the Fourth Amendment. The reasonableness of a search is determined by weighing the government’s interest in collection with the degree to which the search intrudes on privacy. The Court found that although swabbing an arrestee's cheek for DNA collection did constitute a search, the minimal physical invasiveness of the collection technique was important in evaluating the reasonableness of the search. Additionally, arrestees enjoy a diminished expectation of privacy. Kennedy found that the government's interest in identifying arrestees, including discovering one’s criminal history, weighed strongly in favor of collecting DNA samples, as this is a highly effective form of identification. The Court analogized to police practices of taking photographs or collecting fingerprints of arrestees, finding that the DNA collection merely served the same function more effectively. Ultimately, the Court weighed what it characterized as a minimal physical intrusion against the potential of DNA to provide law enforcement with valuable information about arrestees, concluding that DNA collection was a reasonable Fourth Amendment search.
Justice Scalia's four-Justice dissent argued that the Fourth Amendment categorically forbids suspicionless searches justified only by the government's interest in detecting crime. Scalia challenged the majority's assertion that the government’s interest in collection was identification of arrestees, arguing instead that the DNA collection was meant to detect crimes. Such a purpose made the search the type of indiscriminate, general search that the Fourth Amendment was meant to protect against.
- Court Blocks EPIC's Efforts to Obtain "Predictive Analytics Report": A federal court in the District of Columbia has blocked EPIC's efforts to obtain a secret "Predictive Analytics Report" in a FOIA case against the Department of Justice. The court sided with the agency which had withheld the report and asserted the "Presidential communications privilege." Neither the Supreme Court nor the D.C. Circuit has ever permitted a federal agency to invoke that privilege in a FOIA case. EPIC sued the agency in 2017 to obtain records about "risk assessment" tools in the criminal justice system. These techniques are used to set bail, determine criminal sentences, and even contribute to determinations about guilt or innocence. Many criminal justice experts oppose their use. EPIC has pursued several FOIA cases concerning "algorithmic transparency," passenger risk assessment, "future crime" prediction, and proprietary forensic analysis. The case is EPIC v. DOJ (Aug. 14, 2018 D.D.C.). EPIC is considering an appeal. (Aug. 16, 2018)
- EPIC To Congress: Require Transparency for Use of AI: In advance of a hearing on "Artificial Intelligence - With Great Power Comes Great Responsibility," EPIC told the House Science Committee that Congress must implement oversight mechanisms for the use of AI. EPIC said that Congress should require algorithmic transparency, particularly for government systems that involve the processing of personal data. EPIC said that Congress should amend the E-Government Act to require disclosure of the "logic" of algorithms that profile individuals. EPIC also said that the White House Select Committee on Artificial Intelligence should be open to public comment. EPIC has pursued several criminal justice FOIA cases, and FTC consumer complaints to promote transparency and accountability. In 2015, EPIC launched an international campaign for Algorithmic Transparency. (Jun. 25, 2018)

- Whether the Fourth Amendment allows the states to collect and analyze DNA from people arrested and charged with serious crimes.
The Maryland Supreme Court recently considered the constitutionality of certain portions of Maryland's DNA Collection Act, amended in 2008, which allows collection of DNA samples from "individuals arrested for crimes (or attempted crimes) of violence or burglary prior to being found guilty or pleading guilty." King v. State of Maryland, 42 A.3d 549 (Md. 2012). The court in King held that the warrantless collection of defendant Alonzo King's DNA upon his arrest violated the Fourth Amendment. The U.S. Supreme Court then granted certiorari to hear the case.
Alonzo King was arrested in Maryland for assault in April 2009. At the time of his arrest, pursuant to the Maryland DNA Collection Act, police collected a DNA sample from him using a cheek swab. The Act requires law enforcement to collect DNA samples from all individuals arrested for violent crimes. This sample was processed and profiled, then entered into a law enforcement database and compared to DNA profiles from unsolved "cold" cases. King's DNA matched a sample gathered from an unsolved sexual assault in 2003.
With a "hit" from the DNA database as the sole piece of probable cause against King, a grand jury indicted him on ten charges, including rape. The police obtained a search warrant to collect a second DNA sample, via buccal swab, from King to investigate these new charges. The second buccal swab also matched the DNA sample taken from the sexual assault. This new evidence ultimately led to King being convicted of rape and sentenced to life without parole.
The Maryland DNA Act
The Maryland DNA Collection Act was originally enacted in 1994. It authorized the collection of DNA in order to "assist an official investigation of a crime; to identify human remains; to identify missing persons;" and other purposes. In 2008, the Act was amended to allow the State to collect DNA from people arrested for burglary, or violent crimes, at the time of their arrest.
Law enforcement takes the DNA sample from the arrestee, analyzes it, and the resulting profile is entered into the FBI's CODIS database. When DNA is analyzed under the Act, law enforcement specifically targets thirteen sections, or "loci," known as "non-coding" DNA. If the profile creates any "hits" to open cases, this creates probable cause to obtain a warrant for a second DNA sample from the suspect. Only this second sample is admissible as evidence at trial.
The Maryland Supreme Court's Decision
At his sexual assault and rape trial, the court denied King's motion to suppress the DNA evidence. King pled not guilty to the charges in order to preserve his constitutional challenge to the DNA collection. King appealed his conviction to the Maryland Supreme Court, alleging that the warrantless DNA collection was a violation of his Fourth Amendment rights and that the Maryland DNA act was unconstitutional.
The Maryland Supreme Court, after reviewing many similar cases from other jurisdictions, concluded that the DNA Act was unconstitutional as applied in King's case. To reach this conclusion, the court applied the "totality of the circumstances" test laid out by the U.S. Supreme Court in United States v. Knights. That test requires weighing the intrusion upon individual privacy versus the promotion of a legitimate government interest.
The court said that arrestees, unlike convicts or parolees, have strong privacy rights because they are still cloaked with the presumption of innocence until they are found guilty of a crime. "King, as an arrestee, had an expectation of privacy to be free from warrantless searches of his biological material and all of the information contained within that material." The court stated that DNA is fundamentally different from other biological materials. "A DNA sample, obtained through a buccal swab, contains within it unarguably much more than a person's identity. Although the Maryland DNA Collection Act restricts the DNA profile to identifying information only, we can not turn a blind eye to the vast genetic treasure map that remains in the DNA sample retained by the State."
Meanwhile, the interest asserted by the State in this case was weakly attenuated to DNA collection. The State argued that the DNA act sought to further the identification of arrestees. The court disagreed with this argument, noting that DNA analysis is slow, whereas fingerprinting and photographs are much more efficient identification mechanisms. The real purpose of DNA collection, concluded the court, is to further investigation of unsolved crimes.
"Although we have recognized (and no one can reasonably deny) that solving cold cases is a legitimate government interest, a warrantless, suspicionless search can not be upheld by a 'generalized interest' in solving crimes." The court held that the DNA act was therefore unconstitutional as applied to King and reversed the decision of the lower court.
At The U.S. Supreme Court
The State filed a motion with the U.S. Supreme Court to stay the decision pending petition for certiorari. Chief Justice Roberts, applying the Conkright test, granted the stay. "Collecting DNA from individuals arrested for violent felonies provides a valuable tool for investigating unsolved crimes and thereby helping to remove violent offenders from the general population." Chief Justice Roberts noted that the Maryland Supreme Court decision also lessens the effectiveness of law enforcement in other jurisdictions because it removes potential Maryland offenders from the FBI CODIS database. On November 9, 2012, the U.S. Supreme Court granted certiorari to hear the State of Maryland's appeal.
The Question Presented is: "Does the Fourth Amendment allow the States to collect and analyze DNA from people arrested and charged with serious crimes?"
EPIC has a longstanding interest in personal privacy, limiting the government's collection of personal information, and restricting the collection of genetic material. Unlike other biometric data, DNA is more than just an identifier. It is a comprehensive descriptor of all of a person's physical traits and their genealogy. Such valuable personal information must be tightly guarded and restricted to safe, necessary uses. Law enforcement collects and retains complete DNA samples, even though only a few sections are used to create CODIS profiles. There is no statute requiring the federal government to discard the full DNA sample. As genetics researchers discover new ways to use DNA, the potential for misuse by government increases and threatens individual privacy.
When a law enforcement entity collects a DNA sample, the government indefinitely retains that person's full genetic makeup. There is no statute requiring the federal government to discard the full DNA sample. As genetics researchers discover new ways to use DNA, the potential for misuse by government increases and threatens individual privacy. EPIC seeks prevent invasive uses of DNA cataloguing.
EPIC is particularly concerned with the continued expansion of DNA collection from increasingly larger populations; the CODIS database, which once contained only DNA profiles of sex offenders, has expanded to apply to other convicts and parolees. In 2008, the U.S. Attorney General promulgated a regulation that mandated the collection of a DNA sample from every person arrested under federal authority. 28 C.F.R. § 28.12(b). All law enforcement agencies in the country, federal, state and local, have access to CODIS. As CODIS expands, individual privacy rights are implicated, and not just for the individual whose DNA is added to the database; the ability to search for partial matches also implicates the privacy rights of family members whose DNA is a close enough match that the person is flagged in a CODIS DNA search.
Past EPIC "Friend of the Court" Briefs on DNA privacy and law enforcement databases
In 2004, EPIC submitted a 'friend of the court' brief in Maryland v. Raines, 857 A.2d 19 (Md. 2004). This case, a precursor to Maryland v. King, also dealt with a constitutional challenge to Maryland's DNA act. Charles Raines, an incarcerated felon, was forced to submit to a DNA test, which ultimately linked him to an unsolved sexual assault. EPIC argued that the DNA Collection Act violated both the Fourth Amendment and Article 26 of the Maryland Declaration of Rights, Maryland's state constitutional equivalent. The Maryland Court of Appeals held that the Act did not violate Raines's rights because he, as an incarcerated individual, 'enjoy[ed] less liberty than that of ordinary citizens.'
In 2005, EPIC filed a 'friend of the court' brief (PDF) in Kohler v. Englade, 470 F.3d 1104 (5th Cir. 2006), where police in Baton Rouge, Louisiana conducted a house-to-house dragnet to collect DNA samples. EPIC successfully helped affirm that such practices are illegal.
In 2004, EPIC filed a "friend of the court" brief (PDF) in United States v. Kincade, 379 F. 3d 813 (9th Cir. 2004). This case addressed the DNA Analysis Backlog Elimination Act's compulsory DNA collection from parolees. EPIC argued that the statute was unconstitutional under the Fourth Amendment. The court held that an individual already convicted had a lowered expectation of privacy, allowing the DNA collection.
In 2009, EPIC filed a 'friend of the court' brief (PDF) in Herring v. United States, 555 U.S. 135 (2009). In that case, the Supreme Court considered the constitutionality of a police search premised on erroneous information from an inaccurate law enforcement database. EPIC argued that the dramatic expansion of law enforcement databases riddled with inaccuracies and incomplete information puts individuals at risk and jeopardizes criminal investigations. The Court held that the Fourth Amendment only requires the suppression of evidence when doing so would meaningfully deter similar behavior in the future, and when police conduct was sufficiently culpable that such deterrence is worth the price paid by the justice system. Although the Court majority did not exclude the evidence, Justice Ginsburg, writing for four of the Justices in dissent, said that "negligent record-keeping errors by law enforcement threaten individual liberty, are susceptible to deterrence by the exclusionary rule, and cannot be remedied effectively through other means."
In 2005, EPIC submitted administrative comments to the TSA regarding the use of biometric data in access control systems used by workers at the nation's airports. EPIC cited a number of ways in which such biometric systems can be easily defeated, such as by using false identification at enrollment, physical alteration of a personal biometric, skewing sample collection by not cooperating, and hacking into or falsifying the database.
