TORRUELLA, Circuit Judge. Central to this case is the
Federal Bureau of Investigation's ("FBI" or "government") use of
software that it terms a Network Investigative Technique ("NIT").
The FBI used the NIT pursuant to a warrant it obtained from a
magistrate judge in the Eastern District of Virginia (the "NIT
warrant"). The FBI installed the NIT on Playpen, a child
pornography website it had taken over and was operating out of
Virginia. The NIT attached itself to anything that was downloaded
from Playpen, and thus effectively travelled to the computers that
were downloading from the website, regardless of where those
computers were located. The NIT then caused those computers to
transmit several specific items of information -- which would allow
the FBI to locate the computers -- back to the FBI.
One computer the FBI located in this manner belonged to
Alex Levin of Norwood, Massachusetts. After a search of his
computer pursuant to a subsequent search warrant issued in
Massachusetts, the FBI found various media files allegedly
containing child pornography. Levin was indicted and charged with
one count of possession of child pornography, in violation of 18
U.S.C. § 2252A(a)(5)(B). Levin moved to suppress the evidence
seized pursuant to the NIT warrant and the warrant issued in
Massachusetts. The district court granted suppression, United
States v. Levin, 186 F. Supp. 3d 26, 44 (D. Mass. 2016), and the
-2-
government appealed. We disagree with the district court that
suppression is warranted, because the FBI acted in good faith
reliance on the NIT warrant. Accordingly, we vacate the district
court's suppression order and remand for further proceedings.1
I. Background
A. Playpen and the Dark Web
Child-pornography websites are a source of significant
social harm. "[T]he exploitive use of children in the production
of pornography" was already "a serious national problem" decades
ago. New York v. Ferber, 458 U.S. 747, 749 (1982). Modern
technology, which allows images and videos to be "traded with ease
on the [i]nternet," has only amplified the problem. Paroline v.
United States, 134 S. Ct. 1710, 1717 (2014). The child-pornography
website at the center of this case -- and several dozen other cases
throughout the nation2 -- bore the name "Playpen."
1 Recently, both the Eighth and Tenth Circuit reached similar
results in two cases involving the execution of the same NIT
warrant at issue in this appeal. See United States v. Horton, 863
F.3d 1041 (8th Cir. 2017) (reversing the district court's order
suppressing evidence obtained through the NIT warrant, pursuant
to the Leon good-faith exception, even though it determined that
the NIT was void ab initio because the magistrate judge exceeded
her jurisdiction under Rule 41(b)); United States v. Workman, 863
F.3d 1313 (10th Cir. 2017) (reversing the district court's order
suppressing evidence obtained through the NIT warrant, pursuant
to the Leon good-faith exception, without deciding if the
magistrate judge lacked the authority to issue the NIT warrant).

1, 2017 WL 1437511, at *3-4 (N.D. Ala. Apr. 24, 2017) (collecting

Playpen attracted web traffic on a massive scale. Just
between August 2014 and February 2015, more than 150,000 users
accessed the site. Visitors to Playpen made over 95,000 posts on
over 9,000 topics, all pertaining to child pornography. Playpen
also featured discussion forums where its users discussed issues
such as how to groom child victims and how to evade law
enforcement.
Playpen operated on the internet network known as Tor
(short for "The Onion Router"). This network, together with
similar networks, is known as the Dark Web. The United States
Naval Research Laboratory originally created Tor as a means of
protecting government communications. Today, however, the Tor
network is publicly accessible. One gains access to the Tor
network by downloading the Tor software. By masking its users'
actual IP addresses -- which could otherwise be used to identify
users -- that software offers its users much greater anonymity
than do conventional web browsers. Tor achieves this masking by
bouncing users' communications around a distributed network of
relay computers run by volunteers all around the world. The Tor
software can be used to access the conventional internet as well
as the Dark Web.
and categorizing cases).
-4-
Websites on the Dark Web, known as hidden services, can
be reached only by using Tor software, or a similar software.
Playpen was one such hidden service. Unlike websites on the
conventional internet, hidden services cannot be accessed through
public search engines such as Google. Hidden services can be
accessed by using their addresses, if known to the person seeking
to access the hidden service, or by being redirected to them. The
latter can occur when, for instance, a link to a hidden service is
posted on another hidden service and a user clicks that link.
Because Playpen was a hidden service, a Playpen user had
to take several affirmative steps to access the site. First, he
or she needed to download and install the Tor software. Second,
the user would need to acquire the unique web address for Playpen.
Third, the user would use this address to find Playpen in the Tor
Network. And finally, he or she needed to enter a username and
password on Playpen's main page to access the site's content. The
main page displayed "two images depicting partially clothed
prepubescent females with their legs spread apart." Thus,
Playpen's subject matter was obvious even before the user logged
in and accessed the child-pornography content.
B. The Warrants and the NIT
In February 2015, FBI agents seized control of Playpen
pursuant to a warrant (which is not at issue in the present case).
-5-
After seizing control, the FBI continued to run Playpen out of a
government facility in the Eastern District of Virginia for two
weeks, with the purpose of identifying and apprehending Playpen
users.
On February 20, 2015, the government obtained the NIT
warrant from a magistrate judge in the Eastern District of
Virginia. This warrant permitted the FBI to install the NIT on
its server that hosted Playpen, and thereby to obtain information
from "[t]he activating computers [which] are those of any user or
administrator who logs into [Playpen] by entering a username and
password." The warrant authorized the FBI to obtain seven items
of information: (1) the activating computer's actual IP address,
and the date and time that the NIT determines what the IP address
is; (2) a unique identifier generated by the NIT (e.g., a series
of numbers, letters, and/or special characters) to distinguish
data from that of other activating computers, that will be sent
with and collected by the NIT; (3) the type of operating system
running on the computer, including type (e.g., Windows), version
(e.g., Windows 7), and architecture (e.g., x 86); (4) information
about whether the NIT has already been delivered to the activating
computer; (5) the activating computer's Host Name; (6) the
activating computer's active operating system username; and (7)
the activating computer's media access control ("MAC") address.
-6-
After the NIT was installed on the government's server,
it worked in two steps. First, it augmented the content of the
website with additional computer instructions. Once a user or
administrator who had logged into Playpen downloaded such content,
he or she would also download those additional computer
instructions, which comprise the NIT. Then, the NIT would cause
the activating computer to transmit the seven pieces of
information, described above and authorized to be obtained by the
warrant, back to a computer controlled by the FBI. The NIT did
not deny the user of the activating computer access to any data or
functionality of its computer. The NIT allowed the FBI to identify
the IP addresses of hundreds of Playpen users around the country,
including in the Eastern District of Virginia.
Using the NIT, the government determined that a Playpen
user named "Manakaralupa" had accessed several images of child
pornography in early March 2015. The NIT caused Manakaralupa's
activating computer to transmit the aforementioned information to
the government. Using the seized information, the government
traced the IP address of that user to Levin's home address in
Norwood, Massachusetts.
On August 11, 2015, the government obtained a warrant
from a magistrate judge in the District of Massachusetts to search
Levin's home. The government executed the warrant the next day,
-7-
searched Levin's computer, and identified eight media files
allegedly containing child pornography.
On September 17, 2015, Levin was indicted and charged
with one count of possession of child pornography, in violation of
18 U.S.C. § 2252A(a)(5)(B). After Levin moved to suppress all
evidence seized pursuant to the NIT warrant and the warrant
authorizing the search of his home, the district court granted
Levin's motion on May 5, 2016. First, the district court found
that, since the warrant purported to authorize a search of property
located outside the federal judicial district where the issuing
judge sat, the NIT warrant was issued without jurisdiction and
thus was void ab initio. The court reasoned that the magistrate
judge was not authorized to issue it either under Rule 41 of the
Federal Rules of Criminal Procedure 3 or under the Federal
3 Rule 41 has been amended, apparently specifically to permit
magistrate judges to issue warrants such as the NIT warrant. It
now reads:
[A] magistrate judge with authority in any district
where activities related to a crime may have occurred
has authority to issue a warrant to use remote access
to search electronic storage media and to seize or
copy electronically stored information located within
or outside that district if: (A) the district where
the media or information is located has been concealed
through technological means . . . .
Fed. R. Crim. P. 41(b)(6).
Because this amendment became effective on December 1, 2016,
however, it does not apply to the present case. United States v.
-8-
Magistrates Act, 28 U.S.C. § 636(a).4
Second, the district court determined that suppression
was an appropriate remedy because the violation of Rule 41 was
substantive, rather than technical. The court reasoned that,
since the magistrate judge did not have jurisdiction to issue the
warrant, there was no judicial approval. According to the
district court, the resulting search was thus conducted as if not
pursuant to any warrant authorization, and was therefore
presumptively unreasonable.
The district court further concluded that, even if that
error were technical, suppression would still be appropriate, as
Levin demonstrated that he suffered prejudice. The court reasoned
that, had Rule 41(b) been followed, the magistrate judge would not
have issued the NIT warrant, and, therefore, the search conducted
pursuant thereto might not have occurred. Finally, the court
Walker-Couvertier, 860 F.3d 1, 9 (1st Cir. 2017).
4 Section 636(a) of the Federal Magistrates Act reads:
Each United States magistrate judge . . . shall have
within the district in which sessions are held by the
court that appointed the magistrate judge, at other
places where that court may function, and elsewhere
as authorized by law--(1) all powers and duties
conferred or imposed upon United States commissioners
by law or by the Rules of Criminal Procedure for the
United States District Courts . . . .

opined that the good-faith exception did not apply because the
search was conducted pursuant to a warrant that, in its view, was
void ab initio.
II. Discussion
"[W]hen considering a suppression ruling, we review
legal questions de novo and factual findings for clear error."
United States v. Ponzo, 853 F.3d 558, 572 (1st Cir. 2017). We
disagree with the district court's ruling suppressing the evidence
seized pursuant to the NIT warrant. Regardless of whether a Fourth
Amendment violation occurred, the facts of this case show that the
Leon good-faith exception applies.
"The Fourth Amendment contains no provision expressly
precluding the use of evidence obtained in violation" of its terms.
United States v. Leon, 468 U.S. 897, 906 (1984). Nevertheless,
the Supreme Court created the exclusionary rule as a "'prudential'
doctrine . . . 'to compel respect for the constitutional
guaranty.'" Davis v. United States, 564 U.S. 229, 236 (2011)
(first quoting Pa. Bd. of Prob. & Parole v. Scott, 524 U.S. 357,
363 (1998); and then quoting Elkins v. United States, 364 U.S.
206, 217 (1960)). The exclusion of evidence obtained by an
unconstitutional search is "not a personal constitutional right"
but a remedy whose "sole purpose . . . is to deter future Fourth
-10-
Amendment violations." Id. at 236-37 (quoting Stone v. Powell, 428
U.S. 465, 486 (1976)).
Under the exclusionary rule, courts may suppress
evidence "obtained as a direct result of an illegal search or
seizure" as well as evidence that is the "fruit of the poisonous
tree." Utah v. Strieff, 136 S. Ct. 2056, 2061 (2016) (quoting
Segura v. United States, 468 U.S. 796, 804 (1984)). However, due
to the significant costs of suppressing evidence of crimes, the
exclusionary rule applies "only . . . where its deterrence benefits
outweigh its substantial social costs." Id. (quoting Hudson v.
Michigan, 547 U.S. 586, 591 (2006)) (alteration in original).
"[T]he deterrence benefits of exclusion 'var[y] with the
culpability of the law enforcement conduct' at issue. When the
police exhibit 'deliberate,' 'reckless,' or 'grossly negligent'
disregard for Fourth Amendment rights, the deterrent value of
exclusion is strong and tends to outweigh the resulting costs."
Davis, 564 U.S. at 238 (quoting Herring v. United States, 555 U.S.
135, 143-44 (2009) (second alteration in original). However,
"when the police act with an objectively reasonable good-faith
belief that their conduct is lawful . . . or when their conduct
involves only simple, isolated negligence . . . the deterrence
rationale loses much of its force, and exclusion cannot pay its
way." Id. (internal citations and quotation marks omitted).
-11-
The Supreme Court has clearly delineated the bounds of
the good faith exception. Suppression remains appropriate:
1. "[I]f the magistrate or judge in issuing a
warrant was misled by information in an affidavit that
the affiant knew was false or would have known was
false except for his reckless disregard of the truth."
2. "[W]here the issuing magistrate wholly
abandoned his judicial role."
3. Where the executing officer relies "on a
warrant based on an affidavit 'so lacking in indicia
of probable cause as to render official belief in its
existence entirely unreasonable.'"
Leon, 468 U.S. at 923 (citations omitted).
Furthermore, "[t]he Leon good faith exception does not
apply where . . . a warrant . . . is 'so facially deficient--i.e.
in failing to particularize the place to be searched or the things
to be seized--that the executing officers cannot reasonably
presume it to be valid.'" United States v. Woodbury, 511 F.3d 93,
99 (1st Cir. 2007) (citing United States v. Owens, 167 F.3d 739,
475 (1st Cir. 1999)).
Finally, in determining whether a reasonable officer
should have known that a search was illegal despite a magistrate's
authorization, "a court must evaluate all the attendant
circumstances, keeping in mind that Leon requires . . . objective
good faith." United States v. Ricciardelli, 998 F.2d 8, 15 (1st
Cir. 1993) (internal citations omitted).
None of the four conditions identified by Leon apply.
Levin argues that the NIT warrant was akin to a general warrant
-12-
and therefore so obviously lacking in particularity that the
officers' reliance on it amounted to bad faith. See United States
v. Ninety-Two Thousand Four Hundred Twenty-Two Dollars & Fifty-
Seven Cents, 307 F.3d 137, 149 (3d Cir. 2002) (Alito, J.)
(distinguishing between an "overly broad" warrant, under which
evidence "need not be suppressed if the good faith exception
applies," and a warrant that is so "general" that "executing
officers could not have reasonably trusted in its legality"). A
plain reading of the NIT warrant, however, shows otherwise. "The
general warrant specified only an offense . . . and left to the
discretion of the executing officials the decision as to which
persons should be arrested and which places should be searched."
Steagald v. United States, 451 U.S. 204, 220 (1981). In the case
at hand, in contrast, the NIT warrant did not leave to the
discretion of the executing officials which places should be
searched, because the NIT warrant clearly specifies that only
activating computers -- that is "those of any user . . . who logs
into [Playpen] by entering a username and password" -- are to be
searched. The NIT warrant specifies into which homes an intrusion
is permitted (those where the activating computers are located),
and on what basis (that the users in those homes logged into
Playpen). And if the government wished to conduct any further
searches of anyone's home, it would have needed obtain an
-13-
additional warrant -- which is exactly what it did in this case.
Therefore, the NIT warrant "was not so facially deficient that the
executing officers could not reasonably have presumed it to be
valid." Woodbury, 511 F.3d at 100.
We are unpersuaded by Levin's argument that because, at
least according to him, the government was not sure whether the
NIT warrant could validly issue under Rule 41, there is government
conduct here to deter. Faced with the novel question of whether
an NIT warrant can issue -- for which there was no precedent on
point -- the government turned to the courts for guidance. The
government presented the magistrate judge with a request for a
warrant, containing a detailed affidavit from an experienced
officer, describing in detail its investigation, including how the
NIT works, which places were to be searched, and which information
was to be seized.5 We see no benefit in deterring such conduct
-- if anything, such conduct should be encouraged, because it
leaves it to the courts to resolve novel legal issues.6
5 Although Levin protests that the warrant failed to describe the
activating computers as the places to be searched, the request for
a warrant in fact, under the heading "Place to be Searched," states
that the NIT will obtain "information . . . from the activating
computers described below." The request for the warrant goes on
to explain that "[t]he activating computers are those of any user
or administrator who logs into [Playpen] by entering a username
and password."
6 This situation is, of course, distinct from one in which the
government would request and somehow obtain a warrant for conduct
-14-
Thus, we are unpersuaded that there was any bad faith on
the part of the executing officers. The officers acted pursuant
to the warrant. To the extent that a mistake was made in issuing
the warrant, it was made by the magistrate judge, not by the
executing officers, and the executing officers had no reason to
suppose that a mistake had been made and the warrant was invalid.
As discussed above, the NIT warrant was not written in general
terms that would have signaled to a reasonable officer that
something was amiss. The warrant in this case was particular
enough to infer that, in executing it, "the [executing officers]
act[ed] with an objectively 'reasonable good-faith belief' that
their conduct [was] lawful." Davis, 564 U.S. at 238. Under these
circumstances, "the 'deterrence rationale loses much of its
force,' and exclusion cannot 'pay its way.'" Id. (internal
citations omitted).7
Therefore, because the government acted in good faith
reliance on the NIT warrant, and because the deterrent effects on
law enforcement do not outweigh the great cost to society of
suppressing the resulting evidence, suppression is not warranted.
it knows to be illegal.
7 Any deterrent effect is further limited by the fact that Rule
41 has been amended and now appears to allow a magistrate to issue
NIT warrants such as the one at issue here. See supra note 3.
-15-
III. Conclusion
The district court erred in granting the motion to
suppress. Because the executing officers acted in good faith
reliance on the NIT warrant, the Leon exception applies.
Accordingly, the district court's order is vacated, and the case
is remanded for further proceedings not inconsistent with this
opinion.
Vacated and Remanded.
