Edward_M._Davis--William_J._Bratton

Edward Michael Davis (November 15, 1916 – April 22, 2006) was the chief of the Los Angeles Police Department from 1969 to 1978, and later a California state senator from 1980 to 1992 and an unsuccessful Republican candidate for the United States Senate in 1986. Davis' name was familiar to a generation of Americans since it appeared on its own card for "technical advice" in the closing credits of the popular television programs Dragnet (1967–70) and Adam-12 (1968–75).
