New documents were filed in U.S. v. Doug Williams yesterday:

• United States' Proposed Jury Instructions (link fixed) dated 4 May 2015. Among other things, the prosecution wishes the judge to instruct the jury that "[a]n internal investigation conducted by the U.S. Department of Homeland Security into the possible commission of a federal offense" and "[a] pre-employment suitability determination and security background investigation conducted by U.S. Customs and Border Protection" qualify as official proceedings within the meaning of 18 U.S.C. § 1512(b) (Witness Tampering).
  
  
• United States' Requested Voir Dire Questions dated 4 May 2015. The prosecution wishes to identify (and presumably eliminate) any potential jurors who have taken a polygraph "test" before, or who have a family member who has done so, or who have concerns about the use of polygraph examinations.
  
  
• Trial Brief of United States dated 4 May 2015. Prosecution seeks to exclude any evidence or argument regarding the reliability of polygraph examinations, entrapment, or the defendant's prior good acts or lack of a criminal record.
