The main problem I have with analogy to a court of law is witnesses corroboration only works if all the witnesses are describing the same event, or are at least a series of deeply interrelated specific events local on a particular person or place or entity. If witnesses are all talking about a series of separate events all over the globe at different times that aren't associated with each other, those claims are all systematically vulnerable to biases and don't serve to reinforce one another.
