Only parts of Prop 204 were struck down. Asking for ID during a criminal stop has nothing whatsoever to do with Prop 204, that’s just standard procedure.
Once an officer gets an offender to the station for processing, and that offender is identified as an illegal alien, the offender is turned over to ICE for processing.
What really happened with Prop 204 has been heavily misreported by a media sympathetic to the lawless.
Thanks for the clarification.
