Who knows where the bodies are buried?

Say they charge POTUS or go after him for whatever they are all fomenting about. This invokes some type of proceedings where evidence presented. At that point, COHEN knows where the bodies are buried. There was evidence with COHEN or EVIDENCE seized from these people that will be introduced as part of it that implicates the cabal. Maybe COHEN had the CLINTON INSURANCE FILES? Or something else that was raided? Treasure Trove? Then they come after Cohen, he "implicates" POTUS, they do whatever they do and then ALL that evidence comes to light.
