 If I ask you to recall something about your past, you'll go digging around in there. Some of it may be accurate. Some of it may be later recollections that are slightly distorted. Some of it may be your siblings or friends who told you later what happened when you were younger, and that's the memory you're recalling, and so on. And so this is why eyewitness testimony is so problematic in courtrooms. Lawyers know how to ask questions a certain way to get the kind of answer they're looking for.
