dissenting.
Violations of right to counsel may have occurred at the hearings for arraignment and sentence. Defendant has defective intelligence, but the degree of impairment is not clear. We doubt that he waived his right intelligently. See, Johnson v. Zerbst, 304 U. S. 458, 58 S. Ct. 1019, 82 L. Ed. 1461, 146 A. L. R. 357; Moore v. Michigan, 355 U. S. 155, 78 S. Ct. 191, 2 L. Ed. 2d 167. The district court denied a post conviction motion for a psychological examination of defendant. The ruling was plain error for which the judgment should be reversed.
