Police use of DNA samples at issue in Supreme Court case

Posted: February 26, 2013 at 10:48 pm

WASHINGTON (Reuters) - In a case that spotlights the growing use of genetic data by law enforcement agencies, the Supreme Court wrestled on Tuesday with the question of when a DNA sample may be taken from a suspect.

The nine justices peppered lawyers for both sides with tough questions during oral argument as they sought to determine what kind of limits should be put on the right of the government to take samples.

Police and prosecutors in Maryland suffered a major setback when the state's Court of Appeals ruled in April 2012 that Alonzo King's Fourth Amendment right to be free from unreasonable search and seizure was violated when he was required to provide his DNA upon being arrested.

Under Maryland law, samples can be taken from anyone arrested for a serious offense without police needing to get a warrant first. Police can then submit those samples to a national database to see if the suspect is linked with any other crimes.

The case argued on Tuesday focuses purely on samples taken without a warrant after a suspect is arrested and charged with a crime, but not convicted of it. Samples taken from convicted felons are routinely submitted to the national database. That practice is not an issue in the case.

The sample King gave after a 2009 arrest in Wicomico County on two assault charges linked him to a 2003 rape. He was sentenced to life in prison after being convicted of the rape and was convicted of one count of misdemeanor assault on the 2009 charges.

His lawyers argue that the sample taken in the assault arrest should not have been used to link him to the rape.

DIVIDED COURT

During the argument, Justice Samuel Alito, a former U.S. attorney, gave the most strident support for the government's right to take DNA.

"I think this is the most important criminal procedure case this court has heard for decades," he said.

WASHINGTON (Reuters) - In a case that spotlights the growing use of genetic data by law enforcement agencies, the Supreme Court will consider on Tuesday when a DNA sample may be taken from a suspect.

Police and prosecutors in Maryland suffered a major setback when the state's court of appeals ruled in April 2012 that Alonzo King's Fourth Amendment right to be free from unreasonable search and seizure was violated when he was required to provide his DNA upon being arrested.

Under Maryland law, samples can be taken from anyone arrested for a serious offense without police needing to get a warrant first. Police can then submit those samples to a national database to see if the suspect is linked with any other crimes.

The case being argued Tuesday focuses purely on samples taken after a suspect is arrested and charged with a crime, but not convicted of it. Samples taken from convicted felons are routinely submitted to the national database. That practice is not an issue in the case.

The sample King gave after a 2009 arrest in Wicomico County on two assault charges linked him to a 2003 rape. He was sentenced to life in prison after being convicted of the rape and was convicted of one count of misdemeanor assault on the 2009 charges.

His lawyers argue that the sample taken in the assault arrest should not have been used to link him to the rape.

The nine members of the U.S. Supreme Court will review the Maryland court ruling during a one-hour oral argument.

King has received full-throated support from civil liberties groups, which are concerned that the government has too few constraints in collecting DNA. At a minimum, police should be required to get a warrant, based on what lawyers call "individualized suspicion," that links a suspect to a particular crime, King's backers say. There was nothing linking King to the rape until after his DNA was taken and submitted to the database.

Maryland Attorney General Douglas Gansler, a Democrat, said in an interview that the state court decision "didn't make a whole lot of sense to us." He described the law enforcement community in Maryland as being "apoplectic" when the ruling came out.

"The importance of DNA to law enforcement cannot and should not be lost on the justices," Gansler said.

Supreme Court weighs DNA ‘fingerprinting’

Posted: at 10:48 pm

The Supreme Court debated Tuesday whether Marylands decision to collect DNA samples from people arrested for serious crimes represents an unconstitutional invasion of privacy or a crime-solving breakthrough with the potential to be the fingerprinting of the 21st century.

Either way, Justice Samuel A. Alito Jr. said, the case is perhaps the most important criminal procedure case that this court has heard in decades.

DNA tests after arrest? Some justices not so sure

Posted: at 10:48 pm

STORY HIGHLIGHTS

Washington (CNN) -- The U.S. Supreme Court offered a surprising amount of concern Tuesday about states laws allowing police to collect a DNA sample of anyone arrested -- but not yet convicted -- of serious crimes.

A ruling soon on the privacy versus public safety question could have wide-reaching implications in the rapidly evolving technology surrounding criminal procedure.

Law enforcement lauds genetic testing's potential as the "gold standard" of reliable evidence gathering, especially to solve "cold cases" involving violent offenders.

But privacy rights groups counter the state's "trust us" promise not to abuse the technology does not ease their concerns that someone's biological makeup could soon be applied for a variety of non-criminal purposes.

Privacy vs. prosecution: DNA testing gets high court review

The justices raised a host of hypotheticals in their spirited oral arguments, laying out two sharply divided scenarios.

"There is something inherently dangerous about DNA collection that is not the same as fingerprinting," said Justice Sonia Sotomayor. "How far do we let the state go each time it has some form of custody over you in schools, in workplaces, wherever else the state has control over your person?"

"This is what is at stake: Lots of murders, lots of rapes that can be solved using this new technology that involves a very minimal intrusion on personal privacy," said Justice Samuel Alito. "Why isn't this the fingerprinting of the 21st century? What is the difference?"

Twenty-six states and the federal government allow genetic swabs to be taken after a felony arrest and without a warrant.

Can police collect DNA when someone is arrested? Supreme Court to decide

Posted: at 10:48 pm

The US Supreme Court heard argument Tuesday in a case testing whether government officials can routinely collect a persons DNA at the time he or she is arrested and then use that DNA sample to try to link the individual to unsolved crimes.

At issue in the case, Maryland v. King (12-207), is whether taking a DNA sample from an arrestee without first obtaining a court-authorized warrant is an unreasonable search under the Fourth Amendment.

DNA has become an essential law-enforcement tool, not just in its ability to conclusively identify an individual but, more important, through its ability to conclusively link suspects to cold cases.

RECOMMENDED: How much do you know about the US Constitution? A quiz.

In effect, DNA is becoming in the 21st century what fingerprinting was to the 20th except better.

But theres a problem. Unlike a fingerprint, DNA material contains a plethora of highly personal information bound within a persons genetic code. When the government seizes DNA material, it is taking control of more than just the ability to isolate an identifying pattern unique to one individual. With advances in genetic science, DNA might someday reveal information about an individuals susceptibility to future diseases and perhaps even personality traits, scientists say.

Several justices expressed concern that seizing a DNA sample from an individual to solve cold cases is a search under the Fourth Amendment. What justifies the state taking such action without a warrant?, they wanted to know.

Katherine Winfree, Marylands chief deputy attorney general, told the justices that the state did not need to obtain a warrant to collect DNA samples from arrestees because people in police custody have already surrendered a substantial amount of their liberty and privacy.

That cant quite be right, Justice Elena Kagan countered. Assume youve been arrested for something; the state doesnt have a right to go search your house for evidence of unrelated crimes.

Court Appears Conflicted Over DNA Sampling Issue

Posted: at 10:48 pm

The Supreme Court on Tuesday struggled with what one of the justices called its most important criminal procedure case in decades, whether to let police take DNA without a warrant from those arrested in hopes of using it to solve old cases.

Justices seemed conflicted over whether police have a right to take genetic information from people who have only been arrested without getting a judge's approval first, or if the government's interest in solving cold cases trumped the immediate privacy rights of those under police suspicion of other crimes.

One justice seemed to make clear what he thought. "I think this is perhaps the most important criminal procedure case that this court has heard in decades," said Justice Samuel Alito, a former prosecutor.

"This is what is at stake: Lots of murders, lots of rapes that can be solved using this new technology that involves a very minimal intrusion on personal privacy," Alito said later. "Why isn't this the fingerprinting of the 21st century? What is the difference? If it was permissible, and it's been assumed to be so for decades, that it is permissible to fingerprint anybody who's booked, why is it not permissible to take a DNA sample from anybody who is arrested?"

But Chief Justice John Roberts and Justice Elena Kagan questioned how far the government can go if they decide that the police have an interest in people's DNA to help solve cases, with Roberts noting that it wouldn't take much for police to add DNA swabs to traffic stops. "Police officers who give Breathalyzer tests, they can also take a Q-tip or whatever and get a DNA sample, right?" Roberts said.

"It could be any arrestee, no matter how minor the offense," Kagan said. "It could be just any old person in the street. Why don't we do this for everybody who comes in for a driver's license because it's very effective?"

Getting DNA swabs from criminals is common. All 50 states and the federal government take cheek swabs from convicted criminals to check against federal and state databanks, with the court's blessing. But now 28 states and the federal government now also take samples from people who have been arrested for various crimes, long before their guilt or innocence has been proven.

According to court documents, the FBI's Combined DNA Index System or CODIS a coordinated system of federal, state and local databases of DNA profiles contains more than 10 million criminal profiles and 1.1 million profiles of those arrested.

In the case before the court, a 53-year-old woman was raped and robbed but no one was arrested. Almost six years later, Alonzo King was arrested and charged with felony second-degree assault. Taking advantage of a Maryland law that allowed warrantless DNA tests following some felony arrests, police took a cheek swab of King's DNA, which matched a sample from the 2003 Salisbury rape. King was convicted of rape and sentenced to life in prison.

King eventually pleaded guilty to a lesser charge of misdemeanor assault from his arrest, a crime for which Maryland cannot take warrantless DNA samples. The state courts said it violated King's rights for the state to take his DNA based on an arrest alone.

Eric Lander, human genome project leader, weighs in on Supreme Court gene patenting case

Posted: at 10:47 pm

The document, carefully described as Landers personal view, argues that Utah-based Myriad has patented products of nature, which are ineligible for such protection. The patents, Lander argues, are an insurmountable barrier to studying the DNA, with serious repercussions for medical progress.

Although the brief is filed in support of neither party, it is a strong critique of the reasoning that has been used to protect the gene patents that Myriad holds on BRCA1 and BRCA2, breast cancer risk genes for which it sells a diagnostic test. In his brief, Lander proposes a thought experiment, asking the court to consider what would have occurred if such restrictive patents had been taken on HIV.

The patent holder would have been legally entitled to use his patent to block anyone from observing, characterizing or analyzing the virus by any means whatsoever. Scientists would not have been able to rapidly learn the secrets of this insidious virus; drug developers would not have been able to develop life-saving drugs; technologists would not have been able to develop effective diagnostics; and patients would not have been able to know their HIV status, Lander wrote. To their credit, the discoverers of HIV obtained appropriately narrow patents that do not exclude others from observing, characterizing and analyzing naturally occurring HIV.

To build his argument, Lander gets back to basic biology. The federal Circuit Court, which ruled in favor of Myriads patents, had reasoned that the isolated DNA fragments of the human genome patented by Myriad were not products of nature because they required human intervention to be cleaved out of the chromosome.

Lander, however, notes that for three decades, scientists have known that isolated DNA fragments occur naturally. Every time a cell dies, chromosomal DNA is broken into fragments. DNA fragments are found in cells, urine, spit, and stool. They are found in the blood of people with cancer, viral infections, stroke, or traumaand even in samples taken from people who exercise excessively. Analyzing such fragments in a pregnant womans blood is already used as a prenatal test to flag chromosomal disorders in fetuses. Fragments that contain the exact breast cancer genes on which Myriad holds patents were found in two studies, Lander notes.

He goes on to argue that understanding the genome, such as the risks conferred by a gene, is not an invention, but rather is more akin to discovery of a law of Nature.

The Myriad case is due to be heard before the Supreme Court in April. The biotechnology industry argues that if the patents arent upheld, such a decision could erode much of the foundation for a wide array of businesses that range from pharmaceutical companies to agricultural companies. Scientific organizations and patient groups have argued that the patents impede research, and even patients ability to know their own risks.

Lander suggests that the court could rule carefully on the Myriad case without endangering the broader industry. The court could rule as invalid patents on fragments of the human genome, while allowing patents on DNA obtained through a process that involves reverse- engineering a DNA blueprint from other genetic material that produces proteins.

Science is the systematic and cumulative study of the natural world, Lander wrote. For scientific progress to proceed, scientists must have the ability to study the handiwork of Nature.

Central Winger: Sifting through Opta data to sequence the soccer genome

Posted: at 10:47 pm

This network is a visual representation of something I have jokingly begun calling the MLS Player Genome Project.

Using statistics from the Opta's MLS chalkboards and a heavy amount of number crunching, each player (having played at least the minimum minutes required by the high lord sample size) is compared to every other player in MLS. Their positional tendencies and statistical dispositions are each carefully compared and contrasted.

During this process, each pair of players is assigned a similarity score. If this score is above a certain threshold, the representative nodes of the two similar players are connected. Then, using different visual clustering techniques, this enormous matrix of player comparisons is untangled into the visualization seen above.

Complete Central Winger archive

The results are impressive. Forwards are clustered together in blue on the bottom left. Connected to the forwards are attack-minded midfielders in green. The left side of the green cluster seems to be more flank players, while the right side of the cluster seems to have a few more central players.

Moving from the green midfielders, we connect to the red cluster which seems to be home to some more conservative midfielders. And, as expected, this conservatism grows as you move from left to right until you find a handful of prototypical defensive midfielders in Dax McCarty and Kyle Beckerman at the extreme. The fullbacks have their own cluster, featuring players that almost exclusively play wing back. And the goalkeepers, as expected, were pretty easy to statistically pluck out of the crowd.

While these player connections are far from perfect (they are roughly based on mathematical concepts that online dating websites use for personal matching and what Pandora uses for deciphering your musical taste), much value can be gleaned from looking at MLS in this perspective. Strikers and fullbacks, for example, clearly still have very distinct and specific roles. The modern midfield on the other hand is becoming ever more nebulous, to the point that there is no separate cluster for flank midfielders.

Is that a surprise? Not really, since the traditional left and right midfielders commonly featured in a prototypical 4-4-2 are replaced with hybrid attacking wingers more commonly seen in a modern 4-3-3.

As North American soccer continues to grow and improve, I expect this network to become even more illuminating. The tactical game inside the game becomes increasingly sophisticated, so the types of roles that will be required will become even more distinct. A soccer game, after all, is never decided by players playing their positions on a whiteboard; its a series of actions and reactions.
