True, but I think people accept that "know a person", "know a skill", "know a fact", etc are different. I don't think anyone would seriously suggest that the justice system would have made the acquaintance of Bob committing a burglary, or have the skill of Bob committing a burglary -- I think everyone is wondering whether it can be said to know the fact of Bob committing a burglary. I am curious if there's languages that break down "know a fact" further.
