Opinion for the Court filed by Circuit Judge SENTELLE.
Lamar Johnson, a former District of Columbia probationer, appeals from a District Court judgment dismissing his action seeking to enjoin the application of the DNA Analysis Backlog Elimination Act of 2000 (“DNA Act” or “the Act”), 42 U.S.C. §§ 14135-14135e. Johnson argued that the Act violated his constitutional rights under the Fourth Amendment and violated other of his constitutional and statutory rights. Because we conclude that the District Court correctly held that the Act is neither facially unconstitutional nor unconstitutional as applied to Johnson, we affirm.
I
On March 27, 2001, Johnson stole two cars while suffering from “previously untreated emotional and mental health problems.” Shortly after-his arrest, Johnson was taken to a hospital because he was found sitting in a puddle eating dirt. On December 20, 2001, he was convicted in the Superior Court of the District of Columbia on two counts of unarmed robbery in violation of D.C.Code § 22-2801, for *492 which he received a suspended sentence and two years probation.
While Johnson was on probation, the Appellees — agents from the District of Columbia Court Services and Offender Supervision Agency (“CSOSA”) — demanded that Johnson provide a DNA sample for inclusion in the Combined DNA Index System (“CODIS”). The CSOSA agents did not have a warrant and did not have individualized suspicion that Johnson had committed a crime (other than the two counts of unarmed robbery for which he had been convicted and placed on probation). However, the agents claimed that Johnson was obligated under the Act to submit his DNA for inclusion in the CO-DIS database.
The Act provides that CSOSA officials “shall collect a DNA sample from each individual under the supervision of the Agency who is on supervised release, parole, or probation who is, or has been, convicted of a qualifying District of Columbia offense ....” 42 U.S.C. § 14135b(a)(2). Congress left to the District of Columbia the responsibility of determining which offenses should be deemed “qualifying District of Columbia offenses.” Id. § 14135b(d). In turn, the District designated forty-nine separate crimes as “qualifying ... offenses” under the DNA Act, including robbery and carjacking. See D.C.Code § 22^1151(27), (29).
Despite the fact that Johnson was convicted on two counts of a “qualifying offense,” he refused to provide a DNA sample to the CSOSA. A Superior Court judge then ordered Johnson to show cause why his probation should not be revoked because of this refusal to comply with the DNA Act. Prior to the probation-revocation proceeding, Johnson filed a complaint in the United States District Court for the District of Columbia, seeking a temporary restraining order (“TRO”) to prevent the Appellees from requiring him to provide a DNA sample. Before the District Court could rule on the TRO, the parties proposed to resolve the need for emergency injunctive relief. The parties filed a joint motion, under which Johnson agreed to provide a blood sample. The Appellees agreed to delay processing that sample until after his claims in this action and any subsequent appeals had been resolved. The District Court granted the parties’ joint motion and denied Johnson’s motion for a TRO.
Thereafter the Appellees filed a motion to dismiss under Fed. R. Crv. P. 12(b)(1) and Fed. R. Civ. P. 12(b)(6). The District Court concluded — after “[bjalancing the private and public interests” under the totality of the circumstances- — that because probationers have diminished expectations of privacy, Johnson did not state a viable Fourth Amendment claim. The court also rejected Johnson’s claims under the Ex Post Facto Clause, the Fifth Amendment, the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), Pub.L. No. 104-191, 110 Stat.1936, and the International Convention on the Elimination of all Forms of Racial Discrimination (“CERD”). Accordingly, the court granted the Appellees’ motion in full and dismissed the case. This appeal ensued.
II
Johnson raises two claims under the Fourth Amendment. First, Johnson argues it was unconstitutional for the CSO-SA to collect his blood while he was still on probation. Second, Johnson argues it is unconstitutional for the government to retain his DNA profile and “re-search” it in the CODIS database after his probationary term expires (which it now has). We reject both claims.
A
Johnson’s first claim is that collection and storage of his DNA is unconstitutional *493 under the Fourth Amendment, which guarantees that the people shall be “secure in their persons, houses, papers, and effects, against unreasonable searches and seizures .... ” In Johnson’s view, the collection and storage of a probationer’s DNA “[s]trik[es] at the heart of the Fourth Amendment’s most inviolate zone,” and as a result, “these searches must always be predicated on some measure of individualized suspicion.” Because the Act requires every prisoner, probationer, and parolee convicted of a “qualifying offense” to submit his DNA sample without any showing of individualized suspicion, Johnson argues the Act is unconstitutional. For the reasons set forth below, we disagree.
There is no question that the compulsory extraction of blood for DNA profiling constitutes a “search” within the meaning of the Fourth Amendment.
See Skinner v. Ry. Labor Executives’ Ass’n,
Although ordinarily the reasonableness
vel non
of a search depends on governmental compliance with the Fourth’s Amendment’s Warrant Clause,
see, e.g., United States v. U.S. Dist. Court,
After he was convicted, Griffin appealed. Affirming his conviction, the Supreme Court explained:
A State’s operation of a probation system, like its operation of a school, government office or prison, or its supervision of a regulated industry, likewise presents ‘special needs’ beyond normal law enforcement that may justify departures from the usual warrant and probable-cause requirements. Probation, like incarceration, is a form of criminal sanction imposed by a court upon an offender after verdict, finding, or plea of guilty.... [I]t is always true of probationers (as we have said it to be true of parolees) that they do not enjoy the absolute liberty to which every citizen is entitled, but only conditional liberty properly dependent on observance of special probation restrictions.
These restrictions are meant to assure that the probation serves as a period of genuine rehabilitation and that the com *494 munity is not harmed by the probationer’s being at large. These same goals require and justify the exercise of supervision to assure that the restrictions are in fact observed.
Id.
at 873-75,
Notwithstanding
Griffin,
Johnson argues that
“all
law enforcement searches [must] be premised on some quantum of individualized suspicion.” Appellant’s Br. at 20 (emphasis in original). But the Supreme Court has “long held that ‘the Fourth Amendment imposes no irreducible requirement of [individualized] suspicion.’ ”
Bd. of Educ. v. Earls,
vacy entailed by conducting such searches without any measure of individualized suspicion.”
Nat’l Treasury Employees Union v. Von Raab,
Since
Griffin,
the Supreme Court has on only one occasion, considered whether law enforcement officials need individualized suspicion to search a probationer. In
United States v. Knights,
*495
Knowing that Knights’ probation was conditioned on his obligation to submit to suspicionless searches of his person and residence, the police promptly searched Knights’ home without a warrant. They uncovered “a detonation cord, ammunition, liquid chemicals, instruction manuals on chemistry and electrical circuitry, bolt cutters, telephone pole-climbing spurs, drug paraphernalia, and a brass padlock stamped ‘PG & E.’”
Id.
After Knights was arrested and charged, he moved to suppress the evidence.
Id.
at 116,
The Court analyzed the constitutionality of the search of Knights’ apartment under a “totality-of-the-eircumstances” standard rather than the “special needs” doctrine.
Id.
at 117-18,
Inherent in the very nature of probation is that probationers do not enjoy the absolute liberty to which every citizen is entitled. Just as other punishments for criminal convictions curtail an offender’s freedoms, a court granting probation may impose reasonable conditions that deprive the offender of some freedoms enjoyed by law-abiding citizens.
The judge who sentenced Knights to probation determined that it was necessary to condition the probation on Knights’ acceptance of the search provision. It was reasonable to conclude that the search condition would further the two primary goals of probation' — rehabilitation and protecting society from future criminal violations. The probation order clearly expressed the search condition and Knights was unambiguously informed of it. The probation condition thus significantly diminished Knights’ reasonable expectation of privacy.
Id.
at 119-20,
On the other side of the balance is the government’s interest in keeping tabs on a probationer:
[T]he very assumption of the institution of probation is that the probationer is more likely than the ordinary citizen to violate the law. The recidivism rate of probationers is significantly higher than the general crime rate. And probationers have even more of an incentive to conceal their criminal activities and quickly dispose of incriminating evidence than the ordinary criminal because probationers are aware that they may be subject to supervision and face revocation of probation, and possible incarceration ....
4» 4* 'H
The State has a dual concern with a probationer. On the one hand is the hope that he will successfully ... be integrated back into the community. On the other is the concern, quite justified, that he will be more likely to engage in criminal conduct than an ordinary member of the community.... [The State’s] interest in apprehending violators of the criminal law, thereby protecting potential victims of criminal enterprise, may therefore justifiably focus on probationers in a way that it does not on the ordinary citizen.
Id.
at 120-21,
Today we join this unanimous body of authority,
2
and we conclude that the mandatory collection of Johnson’s DNA sample was “reasonable” under the Fourth Amendment’s balancing test. On one side of the balance, it is well settled that probationers have lesser privacy interests than do ordinary citizens.
See Griffin,
Moreover, the privacy invasion caused by a blood test is relatively small (even when conducted on a free citizen).
See Skinner,
*497
In
Jones v. Murray,
the Fourth Circuit considered the applicability of the
Skinner
line of precedent to the collection of blood for DNA identification bank purposes. That circuit held that “[wjhile we do not accept even this small level of intrusion for free persons without Fourth Amendment constraint ... the same protections do not hold true for those lawfully confined to the custody of the state.”
The Fourth Circuit further reasoned that courts must “accept this proposition because the identification of suspects is relevant not only to solving the crime for which the suspect is arrested, but also for maintaining a permanent record to solve other past and future crimes.” Id. Therefore, it cannot be denied that the universal practice of “ ‘booking’ procedures that are followed for every suspect arrested for a felony,” including fingerprinting, ensues without respect to the relevance of fingerprint identification to the suspect’s particular crime. Id. As with fingerprinting, we agree with the Fourth Circuit that “the Fourth Amendment does not require an additional finding of individualized suspicion before blood can be taken from incarcerated felons for the purpose of identifying them.” Id. at 306-07. While we need not decide whether the Fourth Amendment permits the suspicionless collection of blood samples from every suspect arrested for a felony, cf. id. at 306, it certainly permits the collection of a blood sample from a convicted felon, like Johnson, while he is still on probation.
Arguably, Johnson’s privacy interests differ somewhat from those at stake in
Skinner, Schmerber,
and
Jones:
A probationer may have stronger privacy interests than a prisoner, and an individual may have a stronger privacy interest in his permanent identity than he has in the temporary toxicity of his blood. However, we have never held that an
innocent
individual has a Fourth Amendment right to expunge the government’s records
of
his identity.
See Stevenson v. United States,
On the other side of the balance, the government is “quite justified” in taking steps to keep tabs on ex-convicts, to deter recidivism, and to solve past and future crimes.
Knights,
*498 B
Johnson’s second argument is that the Fourth Amendment prohibits the government from storing his “genetic fingerprint” in the CODIS database and “researching” it after he has left the probationary rolls (as he now has). In Johnson’s view, “[o]nce probation ends, the individual’s privacy interest is restored to the level of other citizens while the government’s penal interest disappears.” Appellant’s Br. at 34. Given this reshuffling of the parties’ interests, Johnson argues, the post-probation balance makes it unreasonable to “re-search” ex-convicts’ DNA profiles. For the reasons set forth below, we disagree.
1
After a donor’s DNA is collected under the Act, it is analyzed “in accordance with publicly available standards that satisfy or exceed the guidelines for [the FBI’s] quality assurance program for DNA analysis.” 42 U.S.C. § 14132(b)(1). Using “short tandem repeat” (“STR”) technology, the government creates a “genetic fingerprint” for each donor by looking for the presence of genic variants known as alleles at thirteen specific loci on DNA present in the specimen.
See Kincade,
We conclude that accessing the records stored in the CODIS database is not a “search” for Fourth Amendment purposes. As the Supreme Court has held, the process of matching one piece of personal information against government records does not implicate the Fourth Amendment.
See Arizona v. Hicks,
Johnson attempts to avoid the implications of Hicks by arguing that the installation of a video camera inside someone’s home constitutes one “search,” and a new “search” occurs every time a government official monitors the camera. In Johnson’s view, “[t]he harm from the government’s ability to indefinitely search and re-search [an ex-probationer’s] genetic information [is no different] than placing a video camera in a citizen’s home.” Appellant’s Br. at 30. We reject the analogy.
Monitoring an in-home video camera raises Fourth Amendment concerns where it is tantamount to repetitive, surreptitious surveillance of a citizen’s private goings on.
Cf. United States v. Karo,
Accordingly, we conclude that accessing the DNA snapshots contained in the CO-DIS database does not independently implicate the Fourth Amendment. We note that the consequences of the contrary conclusion would be staggering: Police departments across the country could face an intolerable burden if every “search” of an ordinary fingerprint database were subject to Fourth Amendment challenges. The same applies to DNA fingerprints.
To be sure, genetic fingerprints differ somewhat from their metacarpal brethren, and future technological advances in DNA testing (coupled with possible expansions of the DNA Act’s scope) may empower the government to conduct wide-ranging “DNA dragnets” that raise justifiable citations to George Orwell.
See, e.g., Kincade,
if such dragnet-type law enforcement practices as [Johnson] envisions should eventually occur, there will be time enough then to determine whether different constitutional principles may be applicable. Insofar as [Johnson’s] complaint appears to be simply that scientific devices such as [DNA testing and CODIS] enablef ] the police to be more effective in detecting crime, it simply has no constitutional foundation. We have never equated police efficiency with unconstitutionality, and we decline to do so now.
United States v. Knotts,
2
Johnson also challenges the government’s retention of his blood sample, which he claims might be retested with new technologies in the future. Nothing in the record suggests such future testing is imminent, nor can we analyze its invasiveness until it appears. It is surely not uncommon that evidence of every sort obtained by a lawful search and retained may be useful or provide additional information in the future. If something about some undefined future technology raises constitutional issues, that is a problem for another day.
We are nonetheless advertent to the Supreme Court’s teaching in
Kyllo v. United States,
This is not such a case. Not only is blood testing in common use,
Schmerber,
Ill
Johnson next argues that the federal DNA Act and the District of Columbia’s implementation statute (D.C.Code § 22-4151, which defines a “qualifying District of Columbia offense[]” under the federal DNA Act) violate the Ex Post Facto Clauses of the United States Constitution, art. I, § 9, cl. 3; § 10, cl. 1. In Johnson’s view, the legislative histories of both statutes suggest they were enacted with “punitive intent,” and it is unconstitutional to apply the statutes retroactively to Johnson’s crime, which was committed on March 27, 2001. For the reasons set forth below, we disagree.
A
At the outset, we note that the application of the federal DNA Act to Johnson cannot possibly violate the Ex Post Facto Clause. The federal statute was enacted on December 19, 2000 — more than three months before Johnson committed felonious robbery, and more than one year before Johnson was convicted. Thus, the federal DNA Act does not operate retroactively as to Johnson by its own terms.
See INS v. St. Cyr,
Appellees concede that the District’s implementation statute makes the DNA Act operate retroactively. Thus, the District’s implementation statute may be unconstitutional under the Ex Post Facto Clause if it is “punitive.” As the Supreme Court has held:
If the intention of the legislature was to impose punishment, that ends the inquiry. If, however, the intention was to enact a regulatory scheme that is civil and nonpunitive, we must further examine whether the statutory scheme is so punitive either in purpose or effect as to negate [the District’s] intention to deem it “civil.”
Smith v. Doe,
B
We first consider whether the “purpose” of D.C.Code § 22-4151 was “punitive.” As the Supreme Court has instructed: “Whether [the purpose of] a statutory scheme is civil or criminal is first of all a question of statutory construction.”
Smith,
Nothing in the text or structure of the District’s implementation statute suggests its purpose was “punitive” — the law simply defines the offenses subject to DNA collection under the federal Act.
See
D.C.Code § 22-4151 (requiring forty-nine categories of ex-convicts to donate DNA to CODIS, but adding no substantive requirements — punitive or otherwise — to the federal DNA Act’s requirements). Given the definitional nature of the implementation statute, it can be understood only as a policy judgment by the District’s elected officials regarding which offenses are serious enough to warrant coverage by the federal DNA Act. As the Supreme Court has held, such policy judgments are “an incident of the State’s power to protect the health and safety of its citizens,” and they should be construed “as evidencing an intent to exercise that regulatory power, and not a purpose to add to the punishment.”
Flemming v. Nestor,
Similarly here, the District’s implementation statute simply carried out part of the state’s power to protect the health and safety of its citizens by keeping track of (and deterring future crimes by) ex-convicts. Despite the fact that the statute is codified in the District’s criminal code, it did not create new punishments or increase extant punishments. The statute did create a new obligation for ex-convicts to donate their DNA to the CODIS database; however, a minimally invasive blood test,
Skinner,
C
We next consider whether the “effect” of D.C.Code § 22-4151 is “punitive,” notwithstanding its non-punitive “purpose.” As the Supreme Court has instructed, our inquiry into the effects of the District’s implementation statute should be guided by seven factors, which are “neither exhaustive nor dispositive.”
89 Firearms,
[wjhether the sanction involves an affirmative disability or restraint, whether it has historically been regarded as a punishment, whether it comes into play only on a finding of scienter, whether its operation will promote the traditional aims of punishment — retribution and deterrence, whether the behavior to which it applies is already a crime, whether an alternative purpose to which it may rationally be connected is assignable for it, and whether it appears excessive in relation to the alternative purpose assigned.
Kennedy v. Mendoza-Martinez,
A blood test differs mightily from “an affirmative disability or restraint.” Like a sex-offender registry, the DNA Act “imposes no physical restraint, and so does not resemble the punishment of imprisonment, which is the paradigmatic affirmative disability or restraint.”
Smith,
Finally, Johnson argues that the statutes are “excessive in relation to [any] alternative purpose” that might be assigned to them. However, as the District Court correctly pointed out, the statutory text suggests the DNA Act was enacted, in part, to facilitate DNA-based exonerations.
See
42 U.S.C. § 14132(b)(3)(C) (allowing the use and disclosure of CODIS records for “criminal defense purposes”). The statutory means for accomplishing this “alternative purpose” need not be narrowly tailored: As the Supreme Court has instructed, “[a] statute is not deemed punitive simply because it lacks a close or perfect fit with the nonpunitive aims it seeks to advance.”
Smith,
In sum, the DNA Act and the District’s implementation statute are “punitive” in neither purpose nor effect. Accordingly, we hold the dismissal of Johnson’s ex post facto claim was proper.
IV
We have considered Johnson’s other arguments — which include claims under the Due Process and “equal protection” Clauses of the Fifth Amendment, as well as HIPAA and the CERD — and conclude that they are without merit and do not warrant separate discussion. For the reasons set forth above, the judgment of the District Courtis
Affirmed.
Notes
. Subsequent to
Griffin
the Court has recognized some limits to the "special needs” exception in the context of law enforcement searches.
See Ferguson v. City of Charleston,
. We note that some of these courts have upheld the DNA Act under the "special needs” exception to the warrant requirement,
