Pierce Butler, Donnelley v. United States — Opinion of the Court
“ Those who drafted and passed the enforcement act knew that national prohibition would be assailed by influences more powerful than those that had embarrassed earlier and less sweeping state laws. Experience had shown that it would not do to leave prohibition enforcement officers free to determine what cases should be prosecuted and what ignored, and that mere imposition of duty to report offenders would not be enough. The infliction of punishment for their intentional violations is an appropriate measure to hold them to the performance of their duties. ”
