GU-series "Guardian" police droid

"Put your hands up!"

- A police droid

Police droids were utilized by the Coruscant Security Force (CSF) to assist with law enforcement on the galactic capital planet Coruscant during the waning years of the Galactic Republic. The blue-gray droids had masculine programing and were humanoid in shape with a head that formed into a cylindrical helmet. They patrolled Galactic City and responded to calls either on foot or in RapidResponse police speeders and Coruscant police speeders. Most often, the police droids were the first responders to situations. They created perimeters, questioned witnesses, and collected evidence before handing the cases over to organic police officers and investigators. Police droids were armed with blaster pistols and police batons. The police droids were involved in several cases including the kidnapping of Che Amanwe and Chi Eekway, daughters of Chairman Papanoida of Pantora, and the investigation of the homicide of Rodia Senator Onaconda Farr.

Description
"Drop your weapons and come with us quietly!"

- A police droid

Before and during the Clone Wars, the Galactic Republic used police droids on the capital planet Coruscant to assist organic police officers of the Coruscant Security Force (CSF) in maintaining order on the world. The police droids were humanoid in shape with arms and five-fingered hands, legs, a central torso, and a head. The top of the head formed into a tall, cylindrical helmet. The head also sported glowing, yellow-white photoreceptors and a tiny mouth, which allowed the droids to intake fluids. The units were painted in a blue-gray color scheme and wore the CSF symbol on their helmet, as well as the upper left section of the breastplate. They were programmed as masculine and could speak Basic.

Police droids were equipped with blaster pistols and batons to defend themselves. Their duties included setting up a perimeter, collecting evidence, preliminary interrogations, and holding and arresting suspects. When on patrol, the police droids either traveled on foot or used RapidResponse police speeders and Coruscant police speeders.

History
"That is a stolen vehicle. Put your hands in the air!"

- A police droid, to Padmé Amidala

The CSF had used police droids for some time before the eruption of the Clone Wars. Around 21 BBY, Jedi Master Tera Sinube and Jedi Padawan Ahsoka Tano discovered the lifeless body of a Trandoshan named Nack Movers at his apartment. Police droids were dispatched to assist the Jedi with the investigation. After the two suspects, Ione Marcy and Cassie Cryar, fled the apartment, the police droids gave Sinube a RapidResponse speeder to assist him in tracking the fugitives. Marcy and Cryar were found a short time later by the two Jedi at a train station, and the police droids took Marcy into custody. Cryar was able to slash two police droids with Tano's lightsaber and escape their clutches. However, after a brief hostage standoff, which Tano was able to end, Cryar was also arrested by the police droids.

After Davu Golec of the Republic Ministry of Intelligence was killed by a Death Watch assassin during a secret meeting with Duchess Satine Kryze of the planet Mandalore, a police probe reported to other CSF and Coruscant Guard forces that the Duchess had been the murderer, since she was the only one near the body. The Duchess fled the scene, and the arriving police droids and Coruscant Guard riot troopers chased after her. However, Kryze ducked into an alley to avoid capture. Flying out of the same alley, a driver of a speeder bike was wearing a hood in a similar way to Kryze. Believing that Kryze was the driver of the speeder, police droids in RapidResponse speeders also joined the chase after the speeder. With the attention of the police on the speeder, the Duchess escaped the area.

Police droids assisted CSF Lieutenant Tan Divo in the investigation of the abduction of Che Amanwe and Chi Eekway, the daughters of Pantora Chairman N. Papanoida. During the inspection of Papanoida's apartment on Coruscant, the droids and Divo did not know that the Papanoida's Icon of the Moon Goddess statue had been moved from its original location. Not noticing anything amiss, they failed to see the blood underneath the icon.

During a political debate in the Galactic Senate over the Republic military enhancement bill, several Republic senators were attacked in an attempt at intimidation. One attack was against Naboo Senator Padmé Amidala by two thugs, Chata Hyoki and Robonino, who had been hired by the Separatist Head of State Count Dooku to kill her. Two police droids interfered in the attack, although the thugs shot them and destroyed them by beating their heads on the ground. Amidala escaped in a speeder, with the two assailants in pursuit. Two other police droids noticed the speeding Amidala and also took after her, as the speeder was officially stolen. By the time they caught up to the Senator, she had already shaken the two thugs. Thus the police droids only saw the Senator and no one else; accordingly, they stopped her for the theft of the speeder. Amidala was released from their custody after the situation had been explained, but the two thugs had already escaped. Later, Hyoki and Robonino attacked Alderaan Senator Bail Prestor Organa in the Senate Building parking area. Organa called for help, and his Alderaan Guard engaged the attackers in a firefight. Police droids responded to the scene, and Robonino was hit by one of the Coruscant police speeders driven by a police droid. After the firefight between Hyoki and the Alderaan Guard and CSF droids ended, Hyoki was also taken into custody.

During Lieutenant Divo's investigation of the murder of Rodia Senator Onaconda Farr, police droids assisted the inspector by searching for evidence and providing a backup police presence. They were the first responders at the Coruscant docks after Amidala and Organa were attacked by Farr's assistant and murderer, Lolo Purs. When they arrived, the police droids secured the scene, looked for evidence, and questioned witnesses, including the two Senators. They later placed Lolo Purs under arrest after she was subdued by Senator Amidala.

When bounty hunter Aurra Sing attempted to assassinate Ambassador Yong Dolor, she was captured by Jedi Jyl Somtay. Sing was taken away by several police droids and placed in a restraining container. However, she made the police droids believe that she was unable to breath in the confined space. When the droids opened the container, Sing slammed their heads together and escaped.

By 19 BBY and the end of the Clone Wars, the usage of the police droids by the CSF was phased out.

Behind the scenes
Police droids were first introduced in the Star Wars: The Clone Wars television series episode "Lightsaber Lost," where their voices were performed by Tom Kane. They also appeared and played a prominent role in the episodes "Senate Murders" and "Pursuit of Peace." The "Senate Murders" episode commentary states that the police droids had been used by the CSF for a long time when the Clone Wars began and that they were phased out by the time of the events of Revenge of the Sith. The droids were based on the Keystone Kops, a series of silent film comedies about an incompetent group of policemen. In "Pursuit of Peace," a droid sitting in a police speeder is seen drinking a liquid before spilling it when spotting the speeding Amidala. Whether this was meant to factually describe the need for the droids to intake fluids or if it was simply comic relief has not been clarified.
