I want you to tell me how youth care works in California and bring out the same information for CA that I have done for Sweden. Use a credible source, preferably a government one. I also want you to include what happened when all Division of Juvenile Justice (DJJ) facilities closed effective July 1, 2023, per SB 823? (https://www.cdcr.ca.gov/juvenile-justice/)
