WASHINGTON — A sharply divided Supreme Court on Monday cleared the way for police to take a DNA swab from anyone they arrest for a serious crime, endorsing a practice now followed by more than half the states as well as the federal government.
The justices differed strikingly on how big a step that was.
“Taking and analyzing a cheek swab of the arrestee DNA is, like fingerprinting and photographing, a legitimate police booking procedure that is reasonable under the Fourth Amendment,” Justice Anthony Kennedy wrote for the court’s five-justice majority. The ruling backed a Maryland law allowing DNA swabbing of people arrested for serious crimes.
But the four dissenting justices said the court was allowing a major change in police powers, with conservative Justice Antonin Scalia predicting the limitation to “serious” crimes would not last.
“Make no mistake about it: Because of today’s decision, your DNA can be taken and entered into a national database if you are ever arrested, rightly or wrongly, and for whatever reason,” Scalia said in a sharp dissent which he read aloud in the courtroom. “This will solve some extra crimes, to be sure. But so would taking your DNA when you fly on an airplane — surely the TSA must know the ‘identity’ of the flying public. For that matter, so would taking your children’s DNA when they start public school.”
Maryland Attorney General Doug Gansler agreed that there’s nothing stopping his state from expanding DNA collection from those arrested for serious crimes to those arrested for lesser ones like shoplifting.
“I don’t advocate expanding the crimes for which you take DNA, but the legal analysis would be the same,” Gansler said. “The reason why Maryland chooses to only take DNA of violent criminals is that you’re more likely to get a hit on a previous case. Shoplifters don’t leave DNA behind, rapists do, and so you’re much more likely to get the hit in a rape case.”
