A Long Shot Pays Off in Long Island

A family member shouted “we love you” as police took John Bittrolff back to jail. A court in Long Island had just ordered him held without bail on charges of murdering two women over 20 years ago. “Some arrests take a few hours, some days; some take 20 years,” Suffolk County Police Commissioner Edward Webber told reporters.

If police have the killer, it is a success for “familial searching” — the practice of trawling a database for near misses that are especially likely to arise when the source of traces of DNA recovered from crime scenes or victims are very close relatives of one of the “inhabitants” of the database — convicted offenders or, increasingly, arrestees.

Mr. Bittrolff’s DNA profile was not in the New York database. (He had been arrested, but not convicted, for assault in 1993.) However, last year, his brother, Timothy, had been required to give a sample of DNA after a conviction for violating protective orders. DNA from semen found inside the bodies of both women pointed to a brother of Timothy as the source of that semen. But the two victims were said to have been prostitutes, and Mr. Bittrolff’s counsel have been quick to note that "having sex does not mean killing."

In addition to increasing the modest number of possibly successful “outer directed” database trawls, the case is interesting for some procedural twists involving the acquisition of DNA samples. As in the California “grim sleeper” case, police did not initially seek a court order for a sample of their suspect’s DNA to verify that he was indeed associated with the victim’s bodies. Instead, detectives helped themselves to paper bags of garbage left in front of John Bittrolff's house. Among the plastic cups, drink bottles, toothpicks, straws, crawfish heads, cotton swabs, and bandages, they found DNA from his sons, his brother, and his wife (who they trailed until they collected a cigarette butt that she tossed from the window of her truck while driving to work). And, on one paper cup, they found a DNA profile that matched the semen.

But the police were not satisfied. They arrested wiped DNA from a cup of water John Bittrolff drank after his arrest. And even that was not enough. The assistant district attorney (ADA) then applied for a court order to force the twice-DNA-matched suspect to submit to DNA sampling.

Defense lawyers objected that a third sample from Mr. Bittrolff was manifestly unnecessary. The ADA’s response was that prosecutors are entitled to a "judicially approved" DNA sample to present to a grand jury. The court issued the order, and that is where the case stands as of now.

I cannot say that I understand the prosecutor’s reasoning. Unless New York grand jury procedure is very different from the norm, a prosecutor can introduce all manner of evidence without judicial approval. Grand jurors can even rely on unconstitutionally seized evidence without offending the Fourth Amendment.

Was the ADA looking ahead to the trial? Would he want to avoid having to explain the artifices — the “familial searching,” the personal surveillance of family members, and the garbage pull — that the police used to acquire the earlier samples? He might be able to excise all that from the case with a “judicially approved” sample. In any event, the People will present their evidence to the grand jury on Thursday.

MDNA

According to Wikipedia, "MDNA may refer to
-Mitochondrial DNA (mDNA or mtDNA), the DNA located in organelles called mitochondria
-MDNA (album), a 2012 album by Madonna
-MDNA Tour, 2012 concert tour by Madonna."
Additional research reveals an unexpected relationship between the first and third expansions of the acronym. If Madonna has anything to say about it, her fans seeking unusual souvenirs will have neither mDNA nor any other DNA from the aging pop star on the MDNA tour. She has a "sterilization team" to extirpate any DNA in her dressing room after shows. In fact, the team is concerned with much more than DNA. They remodel the dressing room to include "fake ceilings and fake walls, so they can ensure that no one has hidden a camera somewhere." [1] No "genetic exceptionalism" here.

I have heard that the Secret Service collects the plates, silverware, and drinking glasses or cups the President uses when he is on tour.1/ How about the rest of us? Do we have a reasonable expectation that police will not collect our shed DNA? No court has held that the investigative technique is a search within the meaning of the Fourth Amendment.

Note
  1. The newsletter, DNA: Focus, available from the ACLU of Vermont at http://www.acluvt.org/pubs/focus_dna.pdf, attributes this claim "to the British newspaper, The Sunday Mirror," but a quick web search failed to confirm that the Sunday Mirror or any other publication has made such a statement.

A "Ridiculous" Fourth Amendment Argument in the Grim Sleeper Case?

On January 7, Los Angeles Superior Court Judge Kathleen Kennedy dismissed as "specious and ridiculous" one argument from the alleged "Grim Sleeper" serial killer Lonnie Franklin Jr. [1] According to Mr. Franklin's lawyers, the police violated his Fourth Amendment right to be free from unreasonable searches and seizures when they surreptitiously acquired and analyzed DNA that he left on his plate and utensils at a restaurant.

This is not the first notorious case in which Judge Kennedy has participated. In the prosecution of O.J. Simpson, when she was a municipal judge, she initially limited investigators to 10 hairs from Mr. Simpson's head for microscopic comparisons to hairs found in a blue knit cap lying near the bodies of Nicole Brown Simpson and Ronald Goldman. That "surreal" ruling reflected a lack of understanding of hair comparison protocols. [2, p. 230] However, the Grim Sleeper ruling is more mainstream. No court has treated collecting shed or inadvertently abandoned DNA as a search [3, p. 454]

Apparently, investigators did not want to alert Mr. Franklin that he was suspected of the long series of rapes and murders attributed to the Grim Sleeper. They had a police officer pose as a busboy at John's Incredible Pizza, where Franklin was attending a birthday party. Franklin argued that the officer-busboy cleared his plates — first pizza and then chocolate cake — before he had finished eating. and that this poor service made the collection unconstitutional.

One might not think much would turn on how close Franklin was to completing his repast. From time to time, I have had to tell an eager waiter reaching for my plate to wait -- I am not yet done. If a customer does not speak up, how can he be said to have a protected property interest in the plate, an interest that might trigger Fourth Amendment protection under United States v. Jones, 132 S.Ct. 945 (2012)? Moreover, if a failure to allow the restaurant patron time to eat all he wants is the source of the Fourth Amendment violation, the inevitable discovery exception to the warrant requirement could render the matter academic.

However, Franklin also claimed that he had a reasonable expectation that his plates would be thrown into a pile with others, making his DNA unavailable for testing. This is precisely the argument that the Supreme Court rejected in a questionable opinion in California v. Greenwood, 486 U.S. 35 (1988). In that case, police acquired sealed, plastic bags of trash that their suspect placed on the curb for municipal pickup. Greenwood argued that he expected that the bags would be mixed up with the other garbage in the neighborhood, preserving his privacy interest in the contents of his bags. But the majority of the Court deemed this expectation unreasonable because marauding dogs or curious people might go through the bags before the garbage truck arrived.

Even if that reasoning is convincing, however, the burden on the diner to take other steps to protect his DNA from inspection seems greater than that which Greenwood imposes on people to dispose of some parts of their trash privately. Judge Kennedy reportedly reasoned that "If [Franklin] were really concerned about such things, he would not eat or he would take his trash with him." [1] Is that the kind of world we want to have — one in which people who wish to keep their DNA to themselves must bring their own silverware, plates, and trash bags to restaurants or stay at home for all meals?

Thus, I think that the Fourth Amendment status of police collection of certain forms of shed or discarded DNA is a closer question that the caselaw suggests. There is a plausible argument that at least some surreptitious DNA collection from suspects amounts to a "search." Accepting this argument would not necessarily make this mode of DNA collection and analysis impermissible, for not all searches are unreasonable. But it would require more analysis of the individual and state interests at stake.

The Oral Argument in Maryland v. King — Part IV

The previous installment of this series described counsel’s answers to questions as to how DNA profiling is different from fingerprinting. After pointing out that “there are profound privacy concerns associated with the government's collection of an individual's DNA” because “when you evaluate the entirety of an individual's DNA, there is a great deal of personal information contained there,” counsel for Mr. King added that
Now, the government's response to that is essentially the "just trust us" defense; namely that the government is not looking at all that information, it is only looking at a certain subset of that information. But that has never been how this Court has analyzed privacy interests, at least outside the special needs context. Probably the closest analog is this Court's decision in Kyllo v. United States, where the Court said that it was of no moment that the heat-sensing device that was at issue in that case did not detect any information about the intimate details of activities within the home.
I think this is inaccurate (or at least incomplete, as oral argument often is). First, the Supreme Court has been willing to trust the government with highly private information. Whalen v. Roe, 423 U.S. 1313 (1975), provides an illustration. In Whalen, physicians prescribing, and patients receiving, prescriptions for certain addictive drugs argued that the patients’ right of privacy prevented New York from establishing a database of these drug prescriptions by compelling physicians to send to the state information on “the prescribing physician; the dispensing pharmacy; the drug and dosage; and the name, address, and age of the patient.” That an individual is being treated with powerful medications is profoundly informative, but New York insisted that it could be trusted to use the private information as mandated in the statute. The Court agreed, stating that even though “employees may violate the statute by failing, either deliberately or negligently, to maintain proper security of the computerized data bank, ... [t]here is no support in the record ... for an assumption that the security provisions of the statute will be administered improperly.”

Furthermore, a search warrant must describe with particularity the areas to be searched and the items sought. We trust the state to execute the search in accordance with these limits (although it can take advantage of its observations of other evidentiary items or contraband in plain view). Analogously, in King, the Court can authorize DNA profiling strictly for regions of the genome that are useful for identification but not for drawing inferences about medical conditions or other matters that would not otherwise be apparent in an arrestee.

Second, Kyllo is not particularly analogous to collecting biometric data from an arrestee. The Kyllo Court determined only one thing — thermal-imaging of a home amounted to a search of the premises — even if it was only analogous to a very minor entry into the home (say, opening the door to look at a square inch of the floor). Writing for the Court, Justice Scalia maintained that “[i]n the home, our cases show, all details are intimate details, because the entire area is held safe from prying government eyes.” Moreover, he added, even “the relatively crude equipment at issue here ... might disclose, for example, at what hour each night the lady of the house takes her daily sauna and bath ... .”

Kyllo does not prevent the Court from considering the extent to which a practice that is not comparable to an invasion of the home affects legitimate privacy interests. One needs some further argument to conclude that the nature of the information being acquired is irrelevant. The security-privacy interest in the home is one thing. The pure informational-privacy interest in biometric data is another. The two cannot be automatically equated.

Although the inconclusive Kyllo analogy might play some role in the opinions that ultimately emerge in King, it did not engage any Justices at the oral argument. However, the Chief Justice did evince some doubt about the assertions about deeply private information, for he referred to the ease with which anyone can obtain genetic information:
CHIEF JUSTICE ROBERTS: You disclose all of this intimate private information when you take a drink of water and leave — leave the glass behind.

MR. SHANMUGAM: But, Mr. Chief Justice, as I said at the outset, we believe that there might still be — indeed, we think the better view under this Court's cases is that there would still be a Fourth Amendment search there. The only difference would be that you don't have the intrusion into the body that makes the question of whether or not there is a search here an easy one. ...
The Chief Justice’s question points to the shallowness of the public exposure theory that counsel for Mr. King had used to distinguish DNA molecules from fingerprint images. As I noted yesterday, he seemed to say that fingerprinting was not a search just because the fingers that produce the print are visible in public. If that is enough to defeat a reasonable expectation of privacy for fingerprints, why does not the visibility of bodily fluids that contain the DNA sequences defeat the same expectation for those features?

The better argument is that, whether or not fingerprinting should be considered a search, the informational privacy interest in the entirety of the genome demands treating the acquisition of that information as a search that must be justified under the Fourth Amendment. I am sympathetic to this argument (and have made it myself in Kaye (2001)), but the Court’s opinions on the Fourth Amendment as a guarantee of purely informational privacy are less clear than one might think. It is true that some opinions speak of urinalysis as if it is a Fourth Amendment search in and of itself. But the case usually cited for this proposition, Skinner v. Railway Labor Executives Ass'n, 489 U.S. 602 (1989), involved both an informational privacy concern and disquiet over the manner in which the sample is obtained. In addition to observing that urinalysis could “reveal a host of private medical facts … , including whether [someone] is epileptic, pregnant, or diabetic” the Skinner Court considered the “process of collecting the sample to be tested, which may in some cases involve visual or aural monitoring of the act of urination, [that] itself implicates privacy interests.” Id. at 617.

The Skinner Court may or may not have considered the privacy interest in the act of urination to be critical, but it remains a part of the holding in the case. Skinner therefore does not conclusively resolve the question of what the outcome should be if the procedure the state uses to collect the bodily fluids does not itself offend the Fourth Amendment.

One answer is that it depends on the nature and extent of the information that the laboratory tests reveal. The point here, however, is that Mr. King’s answer that “there would still be a Fourth Amendment search there” is not all that apparent “under this Court’s cases.” (I examine some of these cases further in the articles listed at the end of this posting.)

Justice Alito did not seem inclined to accept the broad view that every form of DNA analysis, divorced from the process of collecting the DNA molecules, is a search “under this Court’s cases.” He asked:
JUSTICE ALITO: What if someone has a bloody shirt and throws it away in the trash — in a public trash can along the street, you are saying that the police can't analyze that without a search warrant?
The unmistakable reference here is to California v. Greenwood, 486 U.S. 35 (1988). There, a police officer acquired opaque, plastic bags left on the curb outside a house and picked up by a private trash collector. She opened the bags and located “items indicative of narcotics use.” The Supreme Court (in an opinion that I and many commentators on the case find less than fully convincing), reasoned
that respondents exposed their garbage to the public sufficiently to defeat their claim to Fourth Amendment protection. It is common knowledge that plastic garbage bags left on or at the side of a public street are readily accessible to animals, children, scavengers, snoops, and other members of the public. ... Moreover, respondents placed their refuse at the curb for the express purpose of conveying it to a third party, the trash collector, who might himself have sorted through respondents' trash or permitted others, such as the police, to do so. Accordingly, having deposited their garbage “in an area particularly suited for public inspection and, in a manner of speaking, public consumption, for the express purpose of having strangers take it,” ... respondents could have had no reasonable expectation of privacy in the inculpatory items that they discarded.
Id. at 40-41. Suppose, then, that the trash also contained Justice Alito’s bloody shirt. It is hard to imagine that the Greenwood Court would have said that a person who has no reasonable expectation that the police will not paw through his garbage for narcotics paraphernalia reasonably could expect that they would not analyze the blood on the shirt.

Without mentioning Greenwood, counsel pointed to a Fourth Circuit opinion:
MR. SHANMUGAM: The argument would be that the subsequent analysis of the DNA nevertheless still constitutes a search. And the most significant decision on this issue to date is the Fourth Circuit's decision in United States v. Davis, which I would encourage you to look at if you are interested in this issue, because it holds that the extraction of the DNA from an item that was lawfully in the government's custody still constitutes a search.
United States v. Davis, 690 F.3d 226 (4th Cir. 2012), is indeed “significant.” It is significantly different from every opinion on “abandoned” or “shed” DNA. Every appellate court to consider traces of saliva on envelopes, cups, bottles, and the like has held that the laboratory analysis is not a search because the individual who left the cells has no reasonable expectation of privacy in the DNA molecules.

Davis does not mention these cases (it is not itself an “abandoned” DNA case),* and the Supreme Court has long endorsed other court of appeals’ opinions treating laboratory analyses of legitimately acquired material as something less than Fourth Amendment searches. See United States v. Edwards, 415 U.S. 800 (1974). Despite these obstacles, the Court of Appeals took the position that even though the police acquired the DNA without violating the Fourth Amendment, and even though the laboratory analysis was confined to the normal, identifying loci, the laboratory work violated a reasonable expectation of privacy and, hence, was a search.

The Supreme Court in King is unlikely to adopt the Fourth Circuit’s position, for it can recognize that swabbing the inside the mouth for cells is a search even if it the government can be trusted to confine its use of the DNA to deriving strictly identifying features. In assessing the constitutionality of the entire DNA database system, it can consider how destructive that procedure is of personal integrity and informational privacy without embracing the conclusion that the mere act of “reading” the DNA is, in and of itself, a search.

Note

* The facts in Davis are rather unusual. Earl Davis showed up at a hospital saying that a robber had shot him in the leg. A police officer took went to interview him there. The officer took Davis’s street clothes, which were in a plastic bag under the hospital bed. The Fourth Circuit determined that the warrantless seizure was permissible because the clothes were in plain view and plainly were relevant to an investigation of the alleged robbery. The investigation led nowhere, but police later used the clothes to obtain Davis’s DNA profile in a murder investigation. His DNA exonerated him, but the police placed the DNA profiles in a local DNA database. It matched DNA found in a still-later murder-robbery case, and that was the match that led to Davis’s prosecution and conviction.
