Cool, but SB34 doesn't let this particular set of data be shared with out-of-state agencies for those purposes either.

> 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. This prohibition applies to ALPR database(s) that LEAs access through private or public vendors who maintain ALPR information collected from multiple databases and/or public agencies.
They would not be able to refuse a valid federal warrant, however.
