I have reviewed your request for "LAPD's policy on undocumented adults".
Your request is not “a request for a copy of records that reasonably describes an identifiable record or records” [see Government Code Section 6253(b)]. Your request does not describe the records sought clearly enough to permit my staff to determine whether any responsive documents exist. If you could provide additional information such as dates, a search for responsive records can be conducted.
However, in order to provide something, attached is the current Chief of Detective Notice of May 17, 2017, with the current Enforcement Action Related to Undocumented Persons - Revised.
If you have any questions or concerns regarding this correspondence, simply respond to this email.
