No, it's not Facebook's job to figure that out. If this was an investigation, then it would be the investigating office's job to figure out that. But it's not an investigation, it's a lawsuit, an accusation by one party against another party. The only thing to figure out here is if the accusation is legitimate. This thread started with the GP remarking that the accusation shouldn't be found valid.
To say that it should be found valid because the accused can then separately try to sue another party is not a proper evaluation of the accusation, nor is it demonstrative of a productive legal process (at least in my opinion), nor is it "the entire point of the justice system".
And what impact does that have?
