(CNN) — On Monday, the U.S. Supreme Court ruled police can collect DNA from criminal suspects without first getting a warrant. The vote was a very close 5 to 4.
The ruling involved a Maryland case where a man was convicted of rape based on a DNA sample taken during an arrest on an unrelated assault charge.
The justices concluded DNA swabbing does not violate the Fourth Amendment, which protects people from unreasonable search and seizure.
26 states and the federal government allow genetic swabs to be taken after a felony arrest and without a warrant.
