While it is not the intent of the Legislature in this act to preclude the sharing of information that is currently allowed by both state and federal laws and rules governing those records, it is the Legislature’s intent in this act to preclude any unauthorized purchase or sale of that information.(f) This section shall not be construed to prevent a law enforcement or prosecutorial agency, or any officer, employee, or agent thereof from obtaining telephone records in connection with the performance of the official duties of the agency consistent with any other applicable state and federal law.(g) Nothing in this section shall preclude prosecution under any other provision of law.(h) The Legislature hereby finds and declares that, notwithstanding the prohibition on specific means of making available or obtaining personal calling records pursuant to this section, the disclosure of personal calling records through any other means is no less harmful to the privacy and security interests of Californians. This section is not intended to limit the scope or force of Section 2891 of the Public Utilities Code in any way.(Added by Stats. 2006, Ch. 626, Sec. 1. Effective January 1, 2007.)
