OK, I see, thanks for rehashing.
I wondered whether you were referring to something that had got by me. I had read the post speculating Trump lawyers inducing witnesses to lie, e.g., perhaps paying them. (I kind of think there were threats and/or maybe blackmail, too.) But I had already attached that thought to the idea of #4 flipping, so I regarded that as a single one-and-the-same package, not separating the two. When you mentioned the “obvious”, I thought maybe you were referring to something additional I’d missed. That’s why I asked.
