Honoring police officer J. D. Tippit, killed by Lee Harvey Oswald shortly after the Kennedy assassination, and other officers killed in the line of duty, the memorial slices into the turf on a triangular park west of the city hall plaza. A long, angled, floating tablet with officers’ names and badge numbers rises from the earth, a sunken-and-resurrecting form reminiscent of the Vietnam Veterans Memorial (1982, Maya Lin) in Washington, D.C. A second bar dramatically elevated overhead on nine slender round posts is perforated with the officers’ badge numbers, casting illuminated shadows on the lower tablet.
