JULIA SMITH GIBBONS, Circuit Judge. Defendant-appellant Christopher Aaron appeals his conviction on seventeen counts of making and subscribing a false document under 26 U.S.C. § 7206(1). Aaron provided a false Social Security number on at least 965 W-2Gs that were provided to him each time he won at least $1,200 at various Detroit-area casinos. At trial, Aaron’s defense was that his purpose in providing the false Social Security numbers was to prevent identity theft. On appeal, he now argues that: (1) the district judge erred by not instructing the jury on his good-faith defense; and (2) his trial counsel was ineffective for not requesting a good-faith instruction, not questioning a juror for cause, and not introducing purportedly probative evidence. For the reasons that follow, we AFFIRM Aaron’s conviction.
