Regardless of guilt or not, using this kind of training as evidence against them seems asinine. If you don't have clear evidence and need to resort to this to try to win your case, why are you even filing the case?
My point is that it shouldn't *be* a piece of evidence, at least not for the Prosecution. Maybe the Defense could raise it as an example of them trying to be mindful of monopolistic behaviors and prevent them from taking root.
