Earl Warren,
Grosso v. United States — Dissent
“ Because most forms of gambling have been declared illegal in this country, gamblers necessarily operate furtively in the dark shadows of the underworld. Only by requiring that such individuals come forward under pain of criminal sanctions and reveal the nature and scope of their activities can Congress confidently expect that revenue derived from that outlawed occupation will be subject to the legitimate reach of the tax laws. Indeed, it seems to me that the very secrecy which surrounds the business of gambling demands disclosure. ”
