Today marks the anniversary of the first Baltimore police officer killed in the line of duty. It occurred March 14, 1808, and the officer, Night Watchman George Workner, died the following day. Justice came swiftly, as you'll see in this description from the Officer Down Memorial Page:
Night Watchman Workner was stabbed to death during a jail break of nine inmates from the Baltimore Jail.
The inmates had fashioned pewter keys and picked the locks to their cell doors. Then they attacked the guards with a small knife one of the inmates had obtained. Watchman Workner was stabbed in the side during the escape and died from the wound the following day.
