The Treasury school stemmed from the fact that in 1927 the Bureau of Prohibition’s enforcement of the Volstead Act was a mess. Part of the mess was due to the lack of trained enforcement officers. Illegal searches and seizures by Bureau agents aroused public indignation. Also, they created a serious problem in obtaining convictions of rumrunners and bootleggers.
L. C. Andrews, the Assistant Secretary of the Treasury, became so concerned over the situation that he persuaded Dengler to join the Bureau of Prohibition and to start an enforcement school for the Bureau’s agents. Dengler had argued for years that Federal law enforcement officers should be schooled in their work to be effective and to deserve public confidence.
Dengler selected a few aides and they put together a course of instruction to be given to some 2,500 prohibition agents. Two men were chosen from each of the Treasury’s eighteen districts throughout the country to come to Washington for four weeks of intensive schooling in proper law enforcement procedures.
The theory was that these thirty-six men would qualify themselves as instructors and then return to their home districts to teach what they had learned to other prohibition agents. But the system soon broke down because the district supervisors sabotaged the school.
“I know how to enforce the law without any help from Washington,” one supervisor announced. He had the support of other supervisors.
The truth was that the supervisors were jealous of the men who had been brought to Washington for special training. They also were fearful that they would lose their jobs to the men with superior backgrounds in law enforcement. The result was that the schools were doomed even before they started. By the end of the year, the schools had been discontinued.
Dengler clung stubbornly to his belief that every Federal law enforcement officer should be trained for his job. He persuaded his superiors to let him organize a correspondence course, with the study to be voluntary. Hundreds of agents applied, convincing Dengler that the agents themselves were eager to know more about professional law enforcement.
The idea of a school was resurrected in 1930 by Amos W. W. Woodcock, when he became head of the Prohibition agency. Dengler again went to work to set up a course of study. But when Woodcock left office a few months later, his successor broke up the schools with the remark: “If a man is smart enough to get a job with us, he doesn’t need any training.”
Dengler confided to a friend later, “That was one of the low points of my life. These schools were badly needed by the government to improve the quality of Federal law enforcement. Hardly anyone seemed interested.”
Indeed, for several years it seemed that no one was interested except Dengler and a few of his friends. But in 1937 Secretary of the Treasury Henry Morgenthau recognized that a major weakness in his department was the lack of organized training for new agents. He issued an order for all agencies within the Treasury to participate in a school program.
