The National Commission on Law Observance and Enforcement (also known unofficially as the Wickersham Commission) was a committee established by then U.S. President, Herbert Hoover, on May 20, 1929. Former attorney general George W. Wickersham (1858–1936) chaired the 11-member group, which was charged with surveying the U.S. criminal justice system under Prohibition, and making recommendations for appropriate public policy.
During the 1928 presidential campaign Herbert Hoover supported the Eighteenth Amendment to the United States Constitution (which had introduced nation-wide alcohol prohibition) but he recognized that evasion of the law was widespread and that prohibition had fueled the growth of organized crime.
Commission members included Henry W. Anderson, Newton D. Baker, , William Irwin Grubb, William S. Kenyon, Monte M. Lemann, Frank J. Loesch, Kenneth Mackintosh, Paul John McCormick, and Dean Roscoe Pound of the Harvard Law School. Pioneering American criminologist August Vollmer wrote portions of the report.
From 1929 to 1930, Alger Hiss worked a year in legal research for the general counsel of the "Wickersham Committee" (as William L. Marbury described it in a 1935 letter, in which he sought the support of U.S. Senator George L. P. Radcliffe for the appointment of Alger Hiss to the U.S. Solicitor General's office).
The Commission focused its investigations almost entirely on the widespread violations of national alcohol prohibition to study and recommend changes to the Eighteenth Amendment, and to observe police practices in the states. They observed police interrogation tactics and reported that "the inflicting of pain, physical or mental, to extract confessions or statements... is widespread throughout the country." They released a second report in 1931 that supported Prohibition but found contempt among average Americans and unworkable enforcement across the states, corruption in police ranks, local politics, and problems in every community that attempted to enforce prohibition laws.
