What it's about
The Court refused to hear the case, leaving these questions undecided.
Williamson's petition raised questions about online services' hash-matching searches and the use of evidence from a warrant he called overbroad.
Question presented
1. Whether email service providers and the National Center for Missing and Exploited Children act as government entities when they conduct hash value searches of private email accounts? 2. Whether the private search doctrine applies when email service providers conduct hash value searches of private email accounts, but no human being reviews the alleged contraband located therein? 3. Whether the Good Faith Exception can Apply to Save a Facially Overbroad Search Warrant when the Same Law Enforcement Officer is Both the Affiant and the Executing Officer?
