After steadily rising through the ranks of the city Police Department, Mr. Robinson was named commissioner in 1984 by then-Mayor William Donald Schaefer. He went on to become the state's secretary of public safety and correctional services in Mr. Schaefer's administration and was secretary of juvenile justice under Gov. Parris N. Glendening.
"He was the first person when Schaefer became governor he chose to head a state agency. Schaefer had a huge amount of respect for Bishop," said Mary Ann Saar, former secretary of the Department of Public Safety and Correctional Services.
