I agree to a point but unfortunately, Willmott didn't get the memo that you plant a seed of doubt then move on, leaving it lingering in jurors' minds. She pressed and pressed for certainty so that in the end, it was the witnesses who looked incredulous, as if they couldn't believe what she was asking. And as a result, they were pressed into giving answers which made it quite clear that what she was suggesting was impossible, completely destroying any doubt she was trying to create. And quite possibly insulting the jurors' intelligence in the process, and making them think that she was either desperate or stupid, or both, to press on with certain lines of questioning. For instance, in her overzealous attempt to create doubt about Janeen Demarte's conclusions, by suggesting her work wasn't wasn't thorough, she pressed Demarte to the point where she had to explain three times that the reason she didn't investigate why Travis said certain things was because "he's not alive", ending in this grand finale:
Willmott: So when somebody is not alive, you can't get any information from them. Is that what you mean?
Demarte: From them directly, that's correct, because they're not alive.
