1) Precedents Cited
A. Warrant overbreadth and nexus to probable cause
The panel framed overbreadth using In re Impounded Case (L. Firm), 840 F.2d 196 (3d Cir. 1988), which asks whether
“the scope of the search and seizure authorized by the warrant” exceeds “the ambit of probable cause” in the affidavit.
The court also invoked the “nexus” requirement from United States v. Am. Invs. of Pittsburgh, Inc., 879 F.2d 1087 (3d Cir. 1989),
emphasizing the need for a “sufficient nexus between the evidence to be seized and the alleged offenses.”
To define “overly broad,” the opinion cited United States v. Ninety-Two Thousand Four Hundred Twenty-Two Dollars & Fifty-Seven Cents ($92,422.57),
307 F.3d 137 (3d Cir. 2002), for the proposition that an overly broad warrant authorizes seizure of items for which there is no probable cause.
It further relied on the Seventh Circuit’s pragmatic view in United States v. Bishop, 910 F.3d 335 (7th Cir. 2018),
stressing that device-wide searching may be reasonable when investigators cannot know where relevant files are stored and should not be expected to accept a suspect’s guidance.
B. Compulsory Process Clause and evidentiary exclusions
The governing Third Circuit test came from Government of Virgin Islands v. Mills, 956 F.2d 443 (3d Cir. 1992),
requiring a defendant to show (1) deprivation of the opportunity to present evidence, (2) materiality and favorability, and
(3) that the deprivation was arbitrary or disproportionate to legitimate evidentiary/procedural purposes.
The opinion noted that Third Circuit applications of Mills generally involve governmental action preventing a defense witness from testifying,
citing United States v. Cruz-Jiminez, 977 F.2d 95 (3d Cir. 1992), and Orie v. Sec'y Pa. Dep't of Corr., 940 F.3d 845 (3d Cir. 2019).
The panel emphasized the limited scope of the Compulsory Process right where a witness does testify, referencing
Franklin v. New York, 145 S. Ct. 831 (2025) (Alito, J., respecting denial of certiorari), and contrasting
United States v. Nobles, 422 U.S. 225 (1975), with cases involving outright exclusion of defense witnesses:
Washington v. Texas, 388 U.S. 14 (1967); United States v. Valenzuela-Bernal, 458 U.S. 858 (1982);
and Taylor v. Illinois, 484 U.S. 400 (1988).
On the interaction between constitutional defense rights and evidence rules, the court cited Holmes v. South Carolina, 547 U.S. 319 (2006),
and treated proper application of evidentiary rules—especially relevance under Fed. R. Evid. 402—as ordinarily legitimate rather than “arbitrary.”
For the standard of review of evidentiary rulings, it referenced Great Am. Ins. Co. v. Norwin Sch. Dist., 544 F.3d 229 (3d Cir. 2008).
C. Double Jeopardy, invited error, and plain-error limits
The “receipt + possession” jury-instruction claim was rejected under invited error per United States v. Perrin, 149 F.4th 267 (3d Cir. 2025),
because Daniels jointly proposed the instructions.
For multiplicity/double jeopardy, the opinion relied on United States v. Finley, 726 F.3d 483 (3d Cir. 2013),
and United States v. Rigas, 605 F.3d 194 (3d Cir. 2010) (en banc), for the requirement that offenses be the same “in law and in fact”
to constitute multiple punishments barred by the Double Jeopardy Clause.
But the panel flagged uncertainty about how those holdings interact with the Supreme Court’s elements/means framework in
Descamps v. United States, 570 U.S. 254 (2013), and therefore found no “plain” error.
The constraints of plain-error review were anchored in Molina-Martinez v. United States, 578 U.S. 189 (2016),
quoting United States v. Olano, 507 U.S. 725 (1993), including the requirement that the error be “clear under current law.”
D. Supervised release conditions: discretion, plain error, and digital supervision
For unpreserved challenges to supervised-release conditions, the panel applied plain-error principles while importing a deferential first-prong lens
from United States v. Adair, 38 F.4th 341 (3d Cir. 2022), and recognizing general abuse-of-discretion review in
United States v. Santos Diaz, 66 F.4th 435 (3d Cir. 2023).
On Fourth Amendment considerations for supervised release, the opinion cited United States v. Moore, 111 F.4th 266 (3d Cir. 2024),
cert. denied, 145 S. Ct. 2849 (2025), and analogized to Samson v. California, 547 U.S. 843 (2006), which upheld suspicionless parole searches.
It also relied on United States v. Abrams, 165 F.4th 784 (3d Cir. 2026), and United States v. Jabateh, 974 F.3d 281 (3d Cir. 2020),
for the proposition that plain-error review is not a vehicle for novel legal theories.
On vagueness and whether “computer” covers smartphones, the court applied United States v. Wise, 134 F.4th 745 (3d Cir. 2025),
and reiterated the void-for-vagueness formulation from United States v. Maloney, 513 F.3d 350 (3d Cir. 2008),
quoting United States v. Lee, 315 F.3d 206 (3d Cir. 2003).
2) Legal Reasoning
A. Why the SORNA-evidence warrant was not overbroad
The court treated the SORNA investigation as one in which digital devices can reasonably be expected to contain evidence of residence and reporting status
(e.g., location information, communications, documents, and other digital traces), and it credited the affidavit’s explanation that
evidence may be concealed with deceptive filenames or stored in unexpected locations.
That combination—(i) surveillance-based indicia of residence at the target home and (ii) realistic concealment dynamics—supplied the required “nexus”
and kept the warrant’s scope within the probable-cause “ambit.”
B. Why excluding the brother’s 2012 statements did not violate the Sixth Amendment
Even assuming the Mills framework applied to limits on a witness’s scope of testimony (as opposed to preventing a witness from testifying at all),
the panel held the claim failed at the third prong: the exclusion was rooted in standard evidence rules, chiefly relevance.
The district court viewed the proffered inference—that past child-pornography exposure on the brother’s devices made it meaningfully more likely he accessed
and downloaded pornography onto Daniels’s devices—as too speculative in the factual timeline presented.
Because that was an ordinary Fed. R. Evid. 402 relevance judgment (reviewed deferentially), it was neither “arbitrary” nor “disproportionate.”
C. Double jeopardy: procedural bars and “not plain” error
The “receipt + possession” argument was stopped at the threshold by invited error: Daniels could not attack instructions he helped propose.
For the “possession + access” theory, the panel emphasized the second prong of plain error: even if there is a credible doctrinal argument that the offenses overlap,
uncertainty about the effect of Descamps v. United States on Third Circuit double-jeopardy analysis meant any error was not “clear under current law.”
Without “plainness,” the claim fails regardless of its underlying appeal.
D. Supervised release: record-based justification and statutory authorization for device searches
For financial disclosure, the panel pointed to record facts suggesting atypical spending and potential concealment risks (e.g., expensive hotel stays despite unemployment,
multiple living arrangements), aligning the condition with the statutory goal of protecting the public under 18 U.S.C. § 3553(a)(2)(C).
On plain-error review, it was not “obvious” the district court abused discretion.
For device inspection and monitoring, the court relied heavily on the text of 18 U.S.C. § 3583(d), which expressly permits SORNA registrants to be subject to searches
(a) by law enforcement or probation officers with “reasonable suspicion,” and (b) by “any probation officer in the lawful discharge of the officer's supervision functions.”
That last clause, in the panel’s view, foreclosed a categorical argument that a reasonable-suspicion prerequisite is always required for probation searches/monitoring.
The panel also rejected vagueness by treating smartphones as encompassed by “computer,” consistent with United States v. Wise.
