A saturation patrol is a police or military patrol tactic wherein a large number of officers are concentrated into a small geographic area.[1] Saturation patrols are used for hot-spot crime reduction,[2] DUI checkpoints, and other location-specific patrols. The methodology employs overwhelming force presence, via large concentration of patrol officers, to create a real or perceived omnipresence,[2] in the hopes that it deters crime inside and outside the actual patrol location. Authorities also use them because of riots and riot officers together with horses or dogs can assist.
