Tom C. Clark,
United States v. Calderon — Opinion of the Court
“ In the first place, this evidence is merely corroborating respondent's cash-on-hand admissions and need not comply with the niceties of the annual accounting concept. While the evidence as a whole must show a deficiency for each of the prosecution years, the corroborative evidence suffices if it shows a substantial deficiency for the over-all prosecution period. Independent evidence that respondent understated his income by $30,000 in the same four-year period for which respondent's extrajudicial admissions tended to show a $46,000 deficiency is adequate corroboration. ”
