Sherman Minton,
Bowman Dairy Company v. United States…
“ It would be strange indeed if the defendant discovered some evidence by the use of Rule 16 which the Government was not going to introduce and yet could not require its production by Rule 17 (c) . There may be documents and other materials in the possession of the Government not subject to Rule 16. No good reason appears to us why they may not be reached by subpoena under Rule 17 (c) as long as they are evidentiary. That is not to say that the materials thus subpoenaed must actually be used in evidence. It is only required that a good-faith effort be made to obtain evidence. ”
