(dissenting).
I respectfully dissent on the sole ground that it was erroneous to exclude defendant’s offer to prove that he was singled out in a discriminatory enforcement of law. Yick Wo v. Hopkins, 118 U.S. 356, 6 S.Ct. 1064, 30 L.Ed. 220 (1886); Bolling v. Sharpe, 347 U.S. 497, 74 S.Ct. 693, 98 L.Ed. 884 (1954) ; Cox v. Louisiana, 379 U.S. 536, 85 S.Ct. 453, 13 L.Ed.2d 471 (1965); United States v. Crowthers, 456 F.2d 1074 (4th Cir. 1972).
I would reverse and remand for a new trial.
