There has been cases of questioning reconstructed memories, in Europe there is specifically one trial in France where a group of abused children where proved wrong. It turned out that they got the abusers wrong, not the facts themselves, and they won the trial at the end of a lot of appeals and reinvestigations. But in the public it has had that impact "child abuse can't be proved because memory is unreliable and therapists implant ideas in people". That case or more exactly the way it's been covered by the media has done immense damage for all abused children advocates, trauma survivors and trauma specialists.
What it seems to me is that memory can be fragmented, partial, and eventually reiterated/reaccessed with elements of the present but effects of trauma and the core feelings are accurate. I myself have partial memories and a period of black hole where I really suspect something happened but I have no proof, only bits of things here and there. I can't be certain of who it was, only conjectures. I only realised because I got proven my memory was wrong and that mentally I did patch the missing bit with extension of other periods of time so the black hole would look seamless. But I do trust the feeling. And as it explains and makes more sense than it brings confusion (amnesia does bring confusion), I tend to trust that even if in the detail I don't know and I'm even unsure I want to know. Perhaps that's a case that's a bit different but memory isn't something easy to deal with. There is a Chris Marker film where he says the reverse of remembering isn't forgetting, and that sentence does echo in me in some way. Forgetting we forgot and replacing something significant by a non-event or covering it up with something else would be more of a form of definite, true forgetfulness.
But I wouldn't share these things with people from my family or anyone who has an interest in being comforted by the idea something didn't happen. This also includes most friends. And even very trustworthy people can't bring any form of knowledge since they weren't there, neither. It's hard to live with vanishing black holes.
In another occasion I did have the opportunity to check a very old memory of something I was supposedly way too young to remember, but there were several people who saw it. It was something no one ever told me and by the baffled surprise they had when I said I remembered the kind of details you cannot know if you weren't there, I could tell not only it was true but also perfectly accurate. The precision sometimes is horrific. But there are categories of memories that aren't that clear. Perhaps if I didn't have the external validation for this one I wouldn't find it clear neither. In any way I guess the thing is to learn how to live with the shades and not just being able to tell everything or investigating. We can know for ourselves, to an extent. An event of category
