The program is called "Spotlight" because during a specific period of time, ranging from a few hours or a few days, the attention of every available officer on the force is directed toward dealing with a single issue. On occasion, a particular "spotlight" might be revisited several times; others may be addressed only once. One of the program goals is to keep criminals off balance. The program is based in four fundamental principles. First, it must address public concerns; second, it must address serious crime through a focus on minor crime; third, it must fully exploit corporate partnerships; and fourth, it must feature the maximum presence of officers on the beat. The program targets a combination of 11 major crime-specific and location-specific "spotlighted" topics: carrying of weapons, litter and public nuisance, underage drinking, transport network, vandalism, truancy, drinking in public, licensed premises, street robberies, sporting events, and parks and public places. Data show that "spotlighted" offenses and locations have experienced a significant crime reduction.
