Does the striking of a prospective juror based on race violate the Constitution?

The striking of even a single juror based on race violates the Constitution. See, e.g., United States v. Vasquez-Lopez, 22 F.3d 900, 902 (9th Cir.1994). In this case, the prosecutor struck three African-American prospective jurors. Specifically, the prosecutor used two of his nineteen peremptory challenges to remove the only two African-Americans who had been drawn, passed for cause, and placed in the jury box and who otherwise would have served on the jury. He also used one peremptory challenge to remove the only African-American who had been drawn as an alternate juror. As a result, the prosecutor obtained a jury, and an alternate juror pool, that contained not a single African-American.
