I was on a Jury for a trial that lasted 2 weeks, dozen witnesses. I came away with the impression that there is what happened, what they saw, what they perceived, and what they remembered. And then memories change over time. Doesn't help that most witnesses are ambushed by circumstances. They're muddling through life when something untoward came out of left field. And so weren't forming long term memories.
