Old memories can be awfully flexible. But being no expert, I'd have thunk traumatic memories would be fairly precise about places but not quite so precise about dates. At least, for me, I have some fairly strong memories of a number of events in my past, but I wouldn't be certain about the year in which they occurred, let alone the date, and would arrive at them (approximately) only by dint of calculation.
So rather than just say that any memory will do, I'd probably rule out testimony that didn't include precisely where things happened, but I'd be more flexible about timing.
That's one reason I don't believe Giuffre. She can't pin down where the incidents took place. Nor did she keep a diary. So she just wafts general accusations. She doesn't strike me as trustworthy. She wants more money. She plainly agreed with Epstein to take a one-off payment but now sees other fish in the pond.
But I don't have an opinion about the Maxwell witnesses because I didn't follow the trial closely enough. Maybe their memories are good enough.
