*When there comes before us the taking of DNA from an arrestee for a traffic violation, the Court will predictably (and quite rightly) say, “We can find no significant difference between this case and King.” Make no mistake about it: As an entirely predictable consequence of today’s decision, your DNA can be taken and entered into a national DNA database if you are ever arrested, rightly or wrongly, and for whatever reason." Maryland v. King (2013) No. 12–207, SUPREME COURT OF THE UNITED STATES (Dissenting opinion)
Still waiting for a reply to that...
