United States v. Werdene
188 F. Supp. 3d 431
E.D. Pa.2016Background
- FBI seized and hosted a copy of Playpen (a Tor-hidden child pornography website) on a government server in the Eastern District of Virginia, then sought a warrant to deploy a Network Investigative Technique (NIT) from that server to identify site users.
- The NIT delivered code to users who logged in; it caused "activating" computers to transmit identifying data (including IP addresses) back to the government-controlled server.
- The Virginia magistrate issued the NIT warrant; the NIT later revealed the IP address tied to the Playpen username "thepervert," which investigators traced via Comcast to Gabriel Werdene in the Eastern District of Pennsylvania.
- FBI agents executed a Pennsylvania search warrant for Werdene’s home and seized child pornography; Werdene was indicted and moved to suppress all evidence as fruits of the NIT warrant.
- Werdene argued the Virginia magistrate lacked Rule 41 jurisdiction to authorize a remote search of out-of-district computers, that the Rule 41 violation was constitutional and required suppression, and alternatively that suppression was warranted for prejudice or deliberate disregard.
- The court concluded Rule 41(b) did not authorize the Virginia warrant but denied suppression: Werdene had no reasonable expectation of privacy in his IP address (so no Fourth Amendment violation), and even if constitutional, the good-faith exception and lack of prejudice supported admission.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Validity of NIT warrant under Rule 41(b) jurisdiction | Warrant unlawfully issued in Virginia because the real place to be searched was activating computers located outside that district | FBI argued Rule 41 is flexible and agents reasonably sought a warrant where the seized server (and NIT deployment point) was located | Technically violated Rule 41(b); magistrate lacked jurisdiction to issue a warrant targeting out-of-district activating computers |
| Whether Rule 41 violation is constitutional (Fourth Amendment) | Violation rises to constitutional magnitude and thus requires suppression | Government: no Fourth Amendment violation because defendants lack a reasonable expectation of privacy in IP addresses; even if constitutional, good-faith exception applies | No Fourth Amendment violation: Third Circuit precedent and Smith analogy mean no reasonable expectation of privacy in IP address; violation not constitutional |
| Applicability of exclusionary rule / good-faith exception | Suppression warranted even if nonconstitutional because Rule 41 limits were ignored and defendant prejudiced or government acted deliberately | Government: exclusion is last resort; agents acted in objectively reasonable reliance on warrant issued by neutral magistrate; suppression would not deter judicial error and would impose heavy social costs | Good-faith exception applies: agents acted reasonably and candidly; magistrate’s jurisdictional mistake does not render suppression appropriate |
| Prejudice / deliberate disregard standard for nonconstitutional Rule 41 violations | Defendant claims prejudice (search would not have occurred) and deliberate disregard because remote out-of-district searches are forbidden | Government: no prejudice under Third Circuit’s fundamental fairness test; agents disclosed Tor limitations and did not mislead magistrate | No prejudice or deliberate misbehavior shown; Rule 41 breach did not offend fundamental fairness and suppression denied |
