Law enforcement agencies across the galaxy often rely on automated forces to supplement flesh-and-blood police officers and detectives, though very few wholly turn over such duties to droids. On Coruscant, local police divisions would not be able to patrol the vast reaches of the planet-wide city without the use of droids. These automatons are afforded programming that allow them to harm sentient beings when very specific operational parameters have been met—namely, the breaking of laws and the endangerment of citizens. These droids are beyond corruption and fatigue, though their rigid procedural thinking can be outsmarted by crafty criminals. Automated security is particularly popular in deep space facilities, where organic crews are kept deliberately small to reduce the amount of life support supplies required.
The arrogant Tan Divo placed great weight on his detective skills, giving little thought to how much he relied on the efficiency of police droids to do his job.
Battle droids are programmed for combat and frontline action, but are not specifically designed for the enforcement of laws or interaction with civilians.
During his campaign of terror, the resurrected Darth Maul sliced through security droid patrols at an InterGalactic storehouse station in the Cybloc system.
