From Wiki:
Do we know what the actual exception was for the raid? I'm sure there is plenty of speculation and assumptions, but do we know what exactly they had that allowed them to render attorney client privilege moot?
The crime-fraud exception can render the privilege moot when communications between an attorney and client are themselves used to further a crime, tort, or fraud. In Clark v. United States, the US Supreme Court stated that "A client who consults an attorney for advice that will serve him in the commission of a fraud will have no help from the law. He must let the truth be told."[8] The crime-fraud exception also does require that the crime or fraud discussed between client and attorney be carried out to be triggered.[9] US Courts have not yet conclusively ruled how little knowledge an attorney can have of the underlying crime or fraud before the privilege detaches and the attorney's communications or requisite testimony become admissible
