Court of Appeals for the Seventh Circuit June 19, 1973, 72-1653 (United States v. David Booker)

STEVENS, Circuit Judge.

A jury composed of five black and seven white persons found defendant, a black, guilty of violating 21 U.S. C. § 841(a)(1). In his conduct of the voir dire, the trial judge committed error by refusing to interrogate prospective jurors on the subject of possible racial prejudice.
