Relating to: prohibiting a law enforcement agency from accessing personal data in exchange for payment without a warrant.

AB 667 prohibits law enforcement agencies from paying third parties or government entities for access to an individual's personal data without a warrant. The bill defines "personal data" broadly to include names, location, financial records, health information, browsing history, and device identifiers. It allows exceptions only when a warrant is obtained, during emergencies involving immediate danger, if data is already public, or with the individual's explicit consent. This law directly affects law enforcement agencies and data-sharing companies by restricting how personal information can be acquired for investigations.
