This case focuses on whether the police can take a DNA sample from a person who has been arrested, but not convicted, for a crime. The answer turns out to be yes. So long as a person is arrested under reasonable suspicion and brought to the police station the police have the right to take a DNA sample. This may be good for some people; those who didn’t commit a crime have been able to give a voluntary sample, but the police like this ruling. The problem is that sometimes the DNA may match to a case that has gone cold. In this case Alonzo Jay King was arrested on an assault charge, and the police connected him to a rape from six years earlier. The DNA was the only evidence against him.
The rationale behind the decision is the same as the rationale surrounding fingerprints. The police are working to identify the man they have arrested as well as to see what they have done in the past, as that is a critical factor in how the police will proceed. There are several caveats. The DNA can only be used to help identify the person. It can not be used to look at the clinical history or search for any genetic issues. Kennedy also said that the DNA testing can only be done for serious crimes, though he did not say what that entails.
This ruling will help the police make more arrests because they can now get DNA from the people they arrest. The dissent argue that this testing is an unreasonable invasion of privacy and that similar effects on the efficacy of law enforcement can be achieved by swabbing the DNA of all people who attend public schools.
I think this may be too much of an expansion of police power. I find it frankly kind of scary.
Scalia is, as usual, the funniest when he said “I doubt that the proud men who wrote the charter of our liberties would have been so eager to open their mouths for royal inspection.”
