I, currently, ask for the following as a minimal initial discovery request.
Any and all adverse or negative information contained in the personnel files of any federal or state law enforcement agent who may have worked on this case in any manner. This includes but is not limited to Any “on-the-job” or field training records, training test score results, evidence of credentials having ever been suspended or revoked. The defense does not agree that United States v. Henthorn sets the appropriate standard of production on this issue. In fact some years ago, counsel had a case where the NCIS gave a Henthorn disclosure to the prosecutor that turned out to be substantially and materially false—which surprised the trial counsel at trial.
We can expand the initial request as more information comes to light. I encourage counsel to review United States v. Roberts, 59 M.J. 323 (C.A.A.F. 2004).
