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.
