May all covered persons redact their own SSI?

No, the SSI Federal Regulation, 49 C.F.R. § 1520.9(a)(3), requires covered persons to refer requests by other persons for SSI to TSA, or the applicable DHS component or agency.  Typically requests received from covered persons are tied to State Open Records Requests or court-order production requests due to litigation.  See the SSI training presentation slides on “Processing Record Requests” for more information on submitting these requests to the SSI Program for review and redaction.
