 In part. I have never been a member of OSA, nor have I been an OSA volunteer. However, as part of continental inv training I did go through B0 documentation of the GO. The investigations unit and GO are part of the same evolutionary tree so to speak. After that, the B0 docs became ceded down to OSA (as I assume was most of GO doctrine), so B0 is one of the things inv and OSA shared. So that part is as far as I'm aware official OSA materials. However, the black&tan terminology was something I picked up "live" during talks with OSA, not through B0 mats. That is because while OSA was never eager to cooperate or share info with us, nevertheless inv and OSA responsbilities at times overlapped. So sometimes it turned out we were both working on the same person just from "opposite ends". ---------------------------------------------------------------------------------------------------------------------------- "Scientology is about control.
