United States v. Parker, 553 F.3d 1309 (10th Cir. 2009)
In this case the Court affirmed a conviction for conspiracy to sell unsafe airplane engines with false documentation, finding no abuse of discretion when a defense character witness was asked on cross-examination if it would change his opinion of the defendant "if you found out he had been selling aircraft engines...that were unairworthy," since the questions "did not assume Parker was 'convicted of the
crimes alleged in his case.'"
