GU-series "Guardian" police droid

"Put your hands up!"

- Police droid

Police droids were utilized by the Coruscant Security Force to assist with law enforcement on the galactic capital planet of Coruscant during the waning years of the Galactic Republic. The droids would patrol Galactic City and respond 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 would create perimeters, question witnesses, and collect evidence before handing the cases over to organic police officers and investigators. Police droids were armed with CSF droid blasters and police batons. The police droids were involved in several high profile cases including the kidnapping of Pantora Chairman Papanoida's daughters Che Amanwe and Chi Eekway and the homicide investigation of Senator Onaconda Farr.

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

- Police droid

Before and during the Clone Wars, the Galactic Republic used police droids on the capital planet of Coruscant to assist organic police officers of the Coruscant Security Force in maintaining peace on the planet. The police droids were humanoid in shape with arms, legs, a central torso, and a head. The top of the head formed into a tall, cylindrical helmet. They were painted in a blue and gray paint scheme and wore the CSF symbol on their helmet as well as the upper left section of the breastplate. Police droids were equipped with CSF droid blasters and batons to defend themselves. Their duties included setting up a perimeter, collecting evidence, preliminary interrogations, and holding and/or arresting suspects. When on patrol, the police droids would either be on foot or use RapidResponse police speeder and Coruscant police speeders.

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

- Police droid, to Padmé Amidala

Police droids had been used for quite some time by the CSF before the Clone Wars. When Jedi Master Tera Sinube and Padawan Ahsoka Tano discovered the body of Trandoshan Nack Movers, police droids were dispatched to assist the Jedi with the investigation. After the two suspects, Ione Marcy and Cassie Cryar, fled the scene, the police droids gave Master Sinube a RapidResponse speeder to assist him in tracking the suspects. When Marcy and Cryar were found a short time later at a train station, the police droids took Marcy into custody. Cryar was able to slash two police droids with Tano's lightsaber, but after a brief hostage standoff, she 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, a police probe reported that the Duchess had been the murderer since she was the only one near the body. The Duchess fled the scene and the probes took after her as did the arriving Coruscant Guard riot troopers. Police droids in RapidResponse speeders also joined the chase believing that the duchess was in a speeder. However, Kryze had tricked them into thinking so and managed to escape.

Police droids assisted CSF Lieutenant Tan Divo in the investigation of the abduction of Pantora Chairman Papanoida's daughters Che Amanwe and Chi Eekway. However, the droids did not know that a religious icon had been moved from its original location in Papanoida's Coruscant apartment, so during their search they missed the blood underneath the icon.

During the political fight over the Republic military enhancement bill, several senators were attacked in an attempt at intimidation. One attack was against Senator Padmé Amidala by two thugs, Chata Hyoki and Robonino, who were hired by Separatist leader Count Dooku to kill her. Two police droids interfered in the attack, however, the thugs overwhelmed and destroyed the droids. Senator Amidala escaped in a speeder and the two thugs went after her. Two other police droids saw the speeding Amidala and also took after her as she was on a stolen speeder. Since by the time they caught up to Amidala she had already shaken the two thugs, the police droids only saw the senator and no one else and so stopped her for being on a stolen speeder. She was released after the situation had been explained, but the two thugs had already escaped. Later, the Hyoki and Robonino attacked Bail Prestor Organa in the Senate Building parking area. Organa managed to call for help and his Alderaan Guard engaged the thugs in a firefight. Police droids responded to the scene as well and Robonino was hit by one of the Coruscant police speeders. Hyoki was also taken into custody after a brief continued firefight with the Alderaan Guard and CSF droids.

During the murder investigation of Senator Onaconda Farr by Lieutenant Divo, police droids assisted the inspector by searching for evidence and providing a backup police presence. They were also the first responders to the Coruscant docks after Senators Amidala and Bail Organa were attacked by Senator Farr's assistant and murder, Lolo Purs. When they arrived, the police droids secured the scene and began looking for evidence and questioning 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 think she couldn't breath in the confined space. When the droids opened up the container, Sing overwhelmed them and managed to escape.

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
The police droids were first introduced in the Star Wars: The Clone Wars TV series episode "Lightsaber Lost" and were voiced 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 begin and 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.
