You still can deny the claim of his knowledge bc the fact is trial had happened, 5 ppl convicted, and he was never asked to testify at all, which means 0 knowledge. But none of us know what he saw or not see bc we don't have all the court documents. So pick your words carefully.

One thing for sure is from JJY court doc, which is the owner of ALL chats, we know that only 1 JJY vid got sent in biz gc, the rest are in other gcs, which means biz gc was NOT meant to share those. (And even IF we get Kim court doc I bet it'll confirm this fact about biz gc too)
