When you ask humans however there are all kinds of made-up "facts" they will tell you. Which is the point the parent makes (in the context of comparing to LLM), not whether some legal database has wrong cases.

Since your example comes from the legal field, you'll probably very well know that even well intentioned witnesses that don't actively try to lie, can still hallucinate all kinds of bullshit, and even be certain of it. Even for eye witnesses, you can ask 5 people and get several different incompatible descriptions of a scene or an attacker.
