Where this statement fits

Maryland v. King: Supreme Court upholds DNA swabs of serious-offense arrestees, 5-4

In Maryland v. King, the Supreme Court upheld taking and analyzing a cheek-swab DNA sample after an arrest supported by probable cause for a serious offense and detention in custody. Justice Anthony Kennedy's majority treated the procedure as a reasonable part of booking and identification. Justice Antonin Scalia, joined by Ruth Bader Ginsburg, Sonia Sotomayor and Elena Kagan, dissented. He argued that Maryland was searching for evidence of unrelated crimes, and that the identification rationale did not describe how the system operated.
