From the 9th Circuit Court of Appeals, this summary from Justia:
United States v. Dreyer
Docket: 13-30077
Opinion Date: September 12, 2014
Judge: Berzon
Defendant appealed his conviction of one count of distributing child pornography and one count of possessing child pornography. An NCIS agent investigating online criminal activity of persons in Washington state found evidence of criminal conduct by defendant, a civilian, and gave the information to civilian law enforcement officials.
On appeal, defendant argued that the fruits of the NCIS investigation into his online file sharing should have been suppressed because military enforcement of civilian laws is prohibited. In United States v. Chon, the court held that the Posse Comitatus Act (PCA), 18 U.S.C. 1385, prohibits Army and Air Force military personnel from participating in civilian law enforcement. The court reaffirmed Chon’s
holding that NCIS agents are bound by PCA-like restrictions on direct assistance to civilian law enforcement. In this case, the NCIS agent’s actions amounted to direct assistance to civilian law enforcement and violated the regulations and policies proscribing direct military enforcement of civilian laws. The court found that the district court erred in denying defendant’s motion to suppress where there was abundant evidence that the violation at issue has occurred repeatedly and frequently, and that the government believes that its conduct is permissible. The court remanded for further proceedings.

So the military (NCIS) can’t investigate civilians? Then why is every alphabet soup agency spying on us? What about Five Eyes?
