How have courts interpreted peremptory challenges in the context of race discrimination?

3 We review for clear error a district court's findings of fact as to the racially discriminatory use of peremptory challenges. United States v. De Gross, 960 F.2d 1433, 1442 (9th Cir.1992) (en banc).

4 Although we decide this case in the context of the rights of a defendant, the peremptory challenge is an equally important tool to insure that the government receives a fair trial. Purkett v. Elem, 514 U.S. 765, ----, 115 S.Ct. 1769, 1771, 131 L.Ed.2d 834 (1995) (upholding prosecutor's use of peremptory strike).
