There is an HCOPL of October I think 17th 1971 that Safepointing is made policy in the cult. I don't know if tyrant miscavige has studied it, but OSA certainly has.
I looked in the Technical Bulletins Volume 7 for this which is 1970-1971 and the only things for October are:
6 Oct. Folder Error Summaries (C/S Series l9) 142
8 Oct. Persistent F/N (C/S Series 20) 144
13 Oct. Course Supervisor Corrections 146
18 Oct. Auditor’s Stats on F/N VGI 147
26 Oct. Obnosis and the Tone Scale (reissued l9 Sept. 1974) 148
Do you happen to know where this this HCO PL might be found?
