None of that testimony is particularly probative of this issue (same goes for LR’s testimony that Donna wasn’t involved). Why? Because everything LR knew about these matters came from SG, which in turn came from KM and which, in turn, came from “the Dentist.” At most, this testimony shows what LR understood (or, more accurately, what LR remembers understanding) based on what was passed through multiple layers of the train car conspiracy, which is like a game of telephone designed to ensure that the first and last car know as little as possible about each other. There is much, much stronger evidence of WA’s involvement than LR’s attenuated testimony. Likewise, LR’s testimony that Donna wasn’t involved really just boils down to him not being told she was involved.
