Just like he ordered everything that Mary Sue and the GO did....and then later claimed he didn't know.For almost forty years, many have known and stated that Hubbard was behind what happened to the Mission Holders.
It was not that different from what had happened to Mission Holders Ray Kemp and Alan Walter some years earlier.
It was a pattern. Because it happened to a lot of Mission Holders at once, and preceded a schism, it was notable, and memorable.
Here's a fairly recent statement from Mike Rinder:
"LRH directed exactly what was to be done at the Mission Holders Conference in SFO following the one in Clearwater. The whole thing was recorded so it could be sent to him. He listened to it, sent Miscavige and others commendations, and ordered that the entire transcript be published."
So much for being the 2nd and 3rd Dynamics.
