Frazier v. State
180 So. 3d 1067
Fla. Dist. Ct. App.2015Background
- Appellant Justin Frazier moved to suppress child-pornography evidence found on his computer after a warrant issued based on information obtained with TLO’s Child Protection System (CPS) software; the trial court denied the motion and Frazier appealed.
- CPS automates searches of public peer-to-peer networks (here, Gnutella), querying keywords and collecting publicly exposed metadata (e.g., filenames, file hash values, IP addresses) without infiltrating or downloading content from target computers.
- CPS compares search results to a law-enforcement-managed database of confirmed child-exploitation filenames and hash values, then filters results to peers within the officer’s jurisdiction.
- Investigators use the observed IP address to subpoena the ISP for subscriber identity, which supplied probable cause for a search warrant.
- The court considered federal and state precedent holding that CPS merely aggregates publicly available information and that users who share files on P2P networks lack a reasonable expectation of privacy.
- The court rejected Appellant’s reliance on a district-court decision that turned on the absence of evidence the defendant was sharing files, and affirmed denial of the suppression motion.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether use of CPS to gather P2P-shared file metadata constitutes a Fourth Amendment search | Frazier: CPS use was an illegal warrantless search violating reasonable expectation of privacy | State: CPS only collects publicly exposed information from P2P sharing; no private areas accessed; provides lawful basis for probable cause | Court: No reasonable expectation of privacy in files shared over P2P; CPS collection was not a search and supported probable cause; suppression denied |
