That's fine but he hasn't said that Roddenberry's memos contradict Shatner's recall.
If there is some mutual exclusivity then what it is? Shater remembered Roddenberry wrote notes against the militarization of his concept but had to concede it was there in earlier episodes he had done. He still objected to it though according to Shatner.
But does Shatner cite the actual memos/notes or is it second-hand retelling... i.e a game of telephone?
@Maurice and @Harvey have poured through the available memos — actual documents. First hand sources. Not second-hand retellings based on a faulty human memory.
