The Supreme Court on June 3, 2013, issued their decision in Maryland v. King. The Court stated when officers make an arrest supported by probable cause to hold a suspect for a serious offense and bring him to the station to be detained in custody, taking and analyzing a cheek swab of the arrestee’s DNA is, like fingerprinting and photographing, a legitimate police booking procedure that is reasonable under the Fourth Amendment.
