United States v. Bonds
United States Court of Appeals for the Ninth Circuit
730 F.3d 890 (2013)
Testifying before a federal grand jury investigating steroid use among professional athletes, Barry Bonds (defendant) was asked whether his trainer Greg Anderson ever gave him a self-injectable substance, and responded with a rambling answer ("Statement C") about being a celebrity child who doesn't get into other people's business, which was factually true about his celebrity lineage but did not answer the question; the grand jury later learned the truth about Anderson's PED distribution from other sources and from Bonds himself. A jury convicted Bonds of obstruction of justice under 18 U.S.C. § 1503 based on Statement C, and he appealed to a Ninth Circuit panel.
Whether a factually true but evasive and non-responsive grand jury answer, which implies ignorance the witness does not actually have, can support an obstruction of justice conviction.
