Many F.B.I. officials regard the administration's plan to establish military tribunals as an extreme step that diminishes the F.B.I.'s role because it creates a separate prosecutorial system run by the military.
Now what the heck are the FBI "officials" commenting on the use or non-use of military tribunals? Its not their decision and their input is irrelavent, this is up to the President and the Department of Justice, not the FBI.
I don't think this conclusion is supported by the text of the article.
