 This slight alteration between the drafts will permit the defendant to impeach Cooper, regardless of the substance of his trial testimony, because his trial testimony cannot be consistent with both versions.Thus, unlike Miller, whose documents appear internally consistent and thus will only be admissible if she testifies inconsistently with these documents, Cooper's documents will undoubtedly be admissible.Because of the inevitability that Cooper will be a government witness at trial, this Court can fathom no reason to delay the production of these documents to the defendant, as they will undoubtedly be admissible for impeachment.
