Justice Anthony Kennedy said the collection of DNA was similar to taking fingerprints
The U.S. Supreme Court says the police have the right to collect DNA from people they arrest, regardless of whether they're actually convicted of anything. Legal expert Royal Oakes says it was a narrow 5-4 decision.
The high court justices made the ruling in the case of Maryland's Alonzo Jay King, who was arrested on an assault charge in 2009. Cops took a sample swab from him, and his DNA turned up a hit on a cold rape case. King said the DNA swab amounted to an unreasonable search. Justice Anthony Kennedy said the collection of DNA was similar to taking fingerprints.
