The Takeaway
Yesterday, the Supreme Court upheld the practice of taking DNA samples from people arrested in felony cases, even if they are not charged. The ruling on Maryland v. King was made in a 5-4 decision.  In the majority opinion, Justice Anthony Kennedy wrote: "Taking and analyzing a cheek swab of the arrestee's DNA is, like fingerprinting and photographing, a legitimate police booking procedure." Justice Scalia disagreed.
