Playpen warrants (where the seized server was in the Eastern District of Virginia) were valid, and the good faith exception applied because it wasn’t readily apparent that the USMJ exceeded his or her jurisdiction or that that would be a recognizable error. United States v. McLamb, 2018 U.S. App. LEXIS 1914 (4th Cir. Jan. 25, 2018).
The use of an administrative subpoena for third party information as to the names and addresses of account holders communicating with the Philippines about child pornography was reasonable under the Fourth Amendment because there was no reasonable expectation of privacy in that information. After that, search warrants were used to get into the houses and computers. United States v. Shultz, 2018 U.S. Dist. LEXIS 11295 (D. Kan. Jan. 24, 2018).*
