In my last post on Maryland v. King, I suggested that both proponents and opponents of King should find the philosophical case for a universal DNA database stronger than they might otherwise have thought. Obviously, moving in that direction — or even including mere suspects in a database — would raise legal questions that would merit (and, one hopes, receive) further consideration by the Supreme Court. But how likely is it that the Court will have another opportunity to consider the constitutionality of a statute that continues to draw the line at arrestees?
The Supreme Court’s decision in King was necessarily limited to the fact pattern presented by Maryland’s particular statute authorizing the collection of DNA from arrestees. For instance, the Court repeatedly noted that the Maryland statute at issue limited DNA collection from arrestees to those who had been “charged” (not, in fact, merely arrested) with “serious crimes,” defined as crimes of violence or burglary, or attempts to commit these crimes. (Although Justice Scalia expressed skepticism that, under the Court’s analysis, it would or could find in any subsequent case a limiting principle preventing the collection of DNA from, say, those arrested for traffic violations, it is of course possible that the Court could find such a distinction.) The Court also noted that in Maryland, samples may not be processed or added to the database until after arraignment, when a judicial officer “ensures that there is probable cause to detain the arrestee.” The presence of probable cause, and the arrestee’s corresponding reduced expectation of privacy, were “fundamental” to the Court’s decision to uphold the collection of DNA from “arrestees.” The Court also noted that samples must be expunged if the arrestee is not convicted. Finally, the Maryland statute strictly limits use of the DNA database to solving cold cases and identifying remains and missing persons; use of the database for other purposes (research, to test for paternity, to analyze health or other traits) is criminalized. The Court explicitly said that a database that was not so limited would raise additional privacy concerns that would require a new analysis.
As usual, it’s more likely that the Court will have another opportunity to examine the constitutionality of DNA collection from arrestees if a circuit split arises regarding one or more of these or other practices. And that, in turn, depends, on how widely states and the federal government vary in their authorizing statutes. An Urban Institute report from May 2013 suggests that variation is, in fact, widespread on these potentially constitutionally relevant factors:
Seriousness of offense
Of the 28 arrestee DNA states, 13 collect DNA from those arrested or charged with any felony; 14 (like MD) collect only from a subset of felonies, typically involving violence, sexual assault, or property crimes; 7 collect from anyone arrested or charged with select misdemeanors; 1 (OK) collects from “any alien unlawfully present under federal immigration law”; and the federal government accepts profiles of any arrestee and any non-US citizen detained by the US government. In addition, 2 states collect DNA immediately upon arrest only if the arrestee has been previously convicted of a felony (CT) or other qualifying crime (TX).
