On May 30, 1975, Dogin was appointed Acting Administrator of the Drug Enforcement Administration (DEA), where he worked in a transitionary period for the DEA.[3] The first Administrator of the Drug Enforcement Administration, John R. Bartels Jr., had resigned amid scandal after being forced out of the administration by Attorney General Edward H.

"LEAA will continue to assist police administrators, lawmakers, and city administrators as they strive to formulate clear direction and guidance to our Nation's law enforcement officers charged with the awesome responsibility of determining the need and degree of force and ultimately the use of deadly force in violent situations. Intensive and continuous training, appropriate guidelines, practices and controls must be addressed in order to reduce and restrict the use of force and deadly force by police without risking and jeopardizing their lives."[9]
In 1980, LEAA was merged into the Office of Justice Assistance, Research, and Statistics (JARS). On February 8, 1980, President Jimmy Carter nominated Henry S. Dogin as Director of JARS.[1]
