The analysis revealed that the New York Police Department has taken significant steps to improve its ability to control disorders since the Crown Heights disturbance. These steps include the designation of a deputy chief to coordinate the department's planning efforts, the formation of a special disorder control staff to take command during future unrest, the acquisition of special equipment, and the implementation of new procedures that should enhance the quality of major tactical operations. The Department has also conducted extensive training of officers in field exercises and simulated riot situations. The completion of a new citywide plan later this year should also contribute to the department's ability to control future disorders effectively.
