"Accordingly, SB 34 does not permit California LEAs to share ALPR information with private entities or out-of-state or federal agencies, including out-of-state and federal law enforcement agencies."

The article refers to Senate Bill 34, but you’ve posted a link to a Wikipedia article for Senate bill 54. How could the article’s content and assertions be made clearer? Should it have spelled out the numerals?

SB34 != SB54.
