The Chicago Police Department (abbreviated Chicago PD or CPD) is the primary law enforcement in Chicago, appearing in Watch Dogs. With the recent introduction of the Crime Prediction System, police can use the CTOS to identify and locate criminals in a matter of seconds, based on as little as a 911 call.
Most Chicago police personnel wear navy-style uniforms consisting of an external bulletproof vest over a light blue shirt and tie, dark cargo pants, black shoes, and a dark blue jacket with the Chicago Police patch on the left sleeve and the flag of Chicago on the right sleeve. All patrolmen also wear a unique star-shaped badge on the upper left of their vest and some of them will also wear a checkered police cap.
CPD SWAT units wear green uniforms, black boots, black knee and arm protectors, black helmets, and black bulletproof vests. HRR (High-Risk Response) officers wear full black body armor, black helmets with bullet-resistant visors, and communication equipment.
All CPD patrol cars are white with blue stripes on the sides, and bear an emblem on the hood. They say "POLICE SERVICES" on each side of the car. The cars are also equipped with spotlights, Motorola, blue LED lights and emergency sirens.

If Aiden Pearce pulls out a conspicuous firearm in public, fires an unsuppressed weapon, kills someone, runs over a civilian, steals a car (without the Disable Alarm hack), etc., civilians can report him to police. After a successful phone call, a CTOS Scan will search for Aiden's whereabouts. If Aiden fails to evade the CTOS scan, the police will respond immediately and arrive within a few seconds of scan completion and attempt to apprehend Aiden (or open fire if past Heat Level one or after Act III).
If a criminal fires their weapon at the player, the civilians will report the player as the suspect instead. This is possibly due to a glitch, or a developer oversight. Thus, police will target Aiden instead. However, if a criminal shoots directly at the police, they will respond immediately by firing back. The police usually do not shoot at gangsters or mission enemies attacking Aiden unless he is hidden from their sight.
For example, police officers will prioritize shooting at Aiden over gangsters or mission enemies. If, however, the attackers are directly harming officers, they will retaliate with gunfire, provided Aiden is not in sight of them. Officers will become hostile if the player hits their squad car, but if a civilian's car bumps into an occupied patrol car, they will not respond. If a mission enemy opens fire at officers unprovoked, the player will immediately receive a heat level even though they did nothing.
The Police A.I. has a priority system. If a criminal has killed several police officers, Aiden's heat level may be increased, and, if a helicopter is summoned, the marksman will retaliate against the criminal if they open fire at the Helicopter. If Aiden is hiding in a dumpster, the police will ignore Aiden completely (even if the top is open and he is exposed, possibly due to a glitch or developer oversight) and focus on hunting the criminals down and shooting them. Another aspect that can be noticed very easily is if the criminals are kept in a short distance with the Police, and Aiden is kept a long distance from between them, the police may still open fire at Aiden, ignoring the criminals in the process. This can be interrupted by either hiding in an object, or alternatively if the criminals begin shooting at an officer, which will temporarily attract all police attention to them. Sometimes, if the Police spot a Criminal that is visibly armed, they will not invest any effort into apprehending them, and will completely ignore them unless they are being attacked by them for some reason.
Police A.I. "cheats" mostly on Search Mode. In the E3 version of the game, if Aiden evaded the police and they entered Search Mode they would just keep speeding around the map, wondering where he is on the realism level. In the final version, however, this has been adjusted into a more "cheaty" method. When the police enter Search Mode they will always patrol around Aiden's hiding spot, the A.I. pretending it doesn't know where he is, but in reality, knowing his exact whereabouts. There are even many instances where officers will get out of their cruisers and walk directly to the player's hiding spot, thus spotting Aiden relatively easily.
Another strange addition is that when Aiden is hiding in an alleyway and there is a nearby police cruiser, shooting in the air will immediately put the police in Search Mode. Even though they do not know who the shooter is, they will always put the blame on Aiden. If Aiden causes a traffic accident involving a patrol car, they will not react to it and casually drive off as if nothing happened. They will, however, respond against Aiden if they are caught in a steam pipe explosion. They will also respond and chase Aiden if he speeds, collides with a car or runs a red light.
The Police Helicopter usually gives chase during or after heat level 3, depending on the ACT. However, the Police Helicopter is also granted an unfair advantage. It is able to outrun even the fastest of cars, and the marksman's A.I. rarely misses its shots. To overcome this, make constant drifts with a vehicle to lower the sniper's precision. Additionally, the player can kill the sharpshooter, (raising heat and lowering reputation) disable the helicopter using the Disable Helicopter Hacking skill to temporarily disable it, shoot it with the Destroyer to make it flee immediately, or land a hit on it with a grenade launcher. Criminals may also open fire at the helicopter and in response, the marksman will retaliate against the criminals.
They are much more powerful than regular police officers, carrying better weapons than their blue counterparts and boasting better accuracy. Thanks to their body armor, they are also able to take more damage than standard officers. Elites do wear helmets, but functionally, they are useless, as they are still killed by a single headshot from any weapon. SWAT vehicles are also stronger and more deadly than the regular Police patrol cars.
Depending on the player's story progress as Aiden, SWAT teams will begin placing roadblocks consisting of SWAT-variant SUVs during the fourth or fifth heat level, replacing the regular police SUV roadblocks. Like the CPD, they will attempt to run the player off the road. Their roadblocks do not appear in Bad Blood, however.
Each SWAT SUV contains one Elite and one Enforcer. Sometimes there will be two or three Elites. The driver will always be an Enforcer. When on-foot, the Elites will take cover, but the Enforcer will walk slowly (and menacingly) towards the player.
SWAT teams equip different sets of weapons. Their Elites on the ground usually carry MP5 SMGs, although some of them can be seen wielding M1014 semi-auto shotguns. At the same time, their Enforcers make use of SG-90 pump-action shotguns.
Unlike the police, SWAT units do not make any appearances in the campaign or patrol the streets, and will only appear during a Police Pursuit.
Their appearances during pursuits are treated differently when playing as Aiden compared to T-Bone. Depending on the player's progress in the storyline, SWAT teams will be more frequently encountered during later stages of the storyline. During Act I, SWAT teams will only be dispatched at the highest heat level, but not as frequently as regular police officers. However, as soon as the player completes Act I, they will begin making occasional appearances during the fourth heat level. Once the player completes the first two chapters of the story, SWAT teams will become more prevalent. They will occasionally appear at the third heat level, and during the highest heat level, regular patrol vehicles will stop being dispatched and are entirely replaced by SWAT SUVs, making the pursuit much more intense, although police officers will still spawn on-foot and attempt to stop the player.
In Bad Blood, SWAT teams are instead treated similarly to when the player hasn't completed Act I of Aiden's storyline, towards the entire game.
In Multiplayer, the Police A.I seems to be much more flawed than the Singleplayer mode. This can be easily noticeable in the online free-roam mode. If there are two players shooting at the police at the same time, the Police A.I. will focus only on the player who has the highest heat level, ignoring the other player entirely. The Police A.I. will focus on the other player ONLY if the other player with the highest heat level has been killed, or the player with low heat level managed to obtain a much higher heat level than the other player. Obviously, this can cause a huge mess in an area if multiple players are actively shooting at the police at the same time, as more patrol cars and helicopters will be dispatched, focusing only on a single player, ignoring the others.
In Online Hacking or Online Tailing, if the invader opens fire, nobody will report him as a shooter, and thus, no patrol cars will be dispatched. If, however, the player who is being invaded shoots, the civilians will report him and the police will respond to the victim's actions, completely and unfairly ignoring the invader's actions. This also gives the invader an advantage, especially if the player who is being invaded already has a wanted level and is being chased by police.

- "Woah, woah! We got some serious tech issues! Rebooting!" (E3)
- "PH-4 to Squad, we have regained control." (Regaining control)
- "Bugging out. We've taken too much fire."
- "Disengaging. We've taken too much fire."
- "We keep this up and we'll go down. Disengaging."
- "Yeah, we've taken too many hits. Backing off."
- "We need repairs, squad. Bugging out."
- "Critical systems are down, we have to disengage."
- "Uh, PH-5 to Squad, we need to back off or we'll go down here."
- "Marksman down, disengaging."
- "We've lost our marksman, we have to disengage."
- "Marksman down! Disengaging!"
- "PH-2 here, it's looking messy down there. Blackout took out a couple of spotlights, we may have injured... We got people flooding onto the field." (Bottom of the Eighth)
- "You have the right to remain silent. Anything you say... Ah fuck it, you're going down, asshole!" (Enforcers)
- "You girls can go home now. The cavalry's here." (referring to regular police officers)
- "You know who the cops call when they need help? Me!"
- "You think that's gonna stop me? Think again."
- "No more fooling around. It's time we get serious."
- "This is top of the line body armor; you don't stand a chance."
- "That peashooter ain't gonna work on me!"
- (laughs) "Time's running out little man."
- "I'm takin' you down, asshole!"
- "Shit, that actually hurt!"
- "This is wrong, I'm takin' damage!"
- "I don't think I can take much more o' this!"
- "Careful! Don't let 'im get the drop on you."
- "What's with the power?"
- "He's shootin'!"
- "Officer down!"
- "We've been flanked!"
- "We're exposed!"
- "Give yourself up!"
- "I need a burp soda!"
- "Apprehend him!"
- "Apprehend the suspect!"
- "Roger that"
- All police vehicles have "MP" labeled on their license plates, which most likely stands for "Metropolitan Police".
- The livery for the department is a white paint scheme, with a blue stripe on the vehicles' sides. Above the strip, it reads "CITY OF CHICAGO" in blue. On the strip, it reads "POLICE SERVICES" in white letters. The hoods of vehicles that have them feature a central emblem in between two blue rally stripes.
- Originally, patrol cars utilized generic red and blue emergency lighting. This was changed for later E3 presentations and the final release.
- The livery differs from its real-life counterpart in several ways, the most obvious being the addition of hood vinyls and the absence of any and all red-colored identification. The emblem is also different from the CAPS emblem seen in real life, most likely because the city owns the trademark to it.
- The police helicopter has 3 callsigns, suggesting they are all different helicopters. However, there is only one voice actor used for the pilot.
- The pilot often sounds rather enthusiastic whenever the marksman lands a hit on the player.
- The spike strips used by the Chicago PD differ from the fixed location spike strips. The police spike strips in E3 demos are yellow and black and are permanently active. In the final release, the colors were changed to a red and white color scheme more reminiscent of fixed spike strips. They are usually placed right beside the roadblock cars.
- Before Act 3, at the lowest heat level, officers will attempt to arrest the player. The heat level will instantly increase if the player walks away, begins to run, refuses to exit their vehicle, enters a vehicle, or wields a two-handed weapon, resulting in lethal force being used against the player.
- If a blackout hack is used, the heat level will only increase if the player is aggressive towards officers in the darkness, or if the player does not make their getaway swift enough.
- Each story act has its own theme for free roam police chases which is shared with crime prevention activities. These themes are dynamic and have separate pieces for pursuits and searches.
- Act 3's theme is missing in Xbox 360 and Playstation 3 versions of the game, likely due to unforeseen hardware limitations.
- Act 4 and Act 5 share the same theme across all platforms.
- The Chicago Police Department rarely spawns on streets unless in Search Mode. They can be identified on the mini-map as a red and blue flashing hollow diamond and will ignore the player, unless they pull out a gun, speed, collide with other vehicles, etc. No police officers or patrol cars can be found at any downtown Police Station. Patrol cars can only be seen parked at the Wards Police Station.
- When a search begins, in search dialogue can be head before officers actually state the suspect has been lost. The in search dialogue will abruptly cut off for the proper dialogue to play. This is obviously a glitch.
- Only Cruisers can be found patrolling the streets of Chicago, albeit rarely.
- One must be careful with any police car roaming around, as if the player hits the police car (or vice versa), they will become aggressive and start to chase them.
- Climbing on top of a police car is also considered a crime.
- Police officers can commandeer any department vehicle, making it possible to see normal officers in SWAT Polars, or SWAT officers in normal vehicles. (Outside of ctOS Mobile)
- It is not possible for officers to mix and match department divisions. SWAT will only ride with SWAT, and normal officers will only ride with normal officers.
- Police will ignore you completely if you try to harass them by standing close to them for extended periods of time, excessively honking at them, etc.
- Despite the Crown Victoria's ubiquitous nature among police forces throughout the country, the Vessel is only seen utilized by officers during pursuits involving the ctOS mobile app. It is the earliest unit available to ctOS operators, and as such, is the cheapest and weakest unit dispatched after checkpoint-chasing vigilantes.
- Occasionally, WKZ TV will report Aiden on various TVs throughout the city. At this point, all pedestrians will recognize him and will call police after filling a yellow detection meter.
- Even if Aiden steals a car, the civilian will always mention that he is armed with a gun instead of reporting it as car theft. This does not happen with occupied vehicles.
- Usually, dispatch refers to themselves or the PD as "Squad" when a pursuit has been initiated or during a pursuit.
- Police cars will flick their spotlights on only during the night or when the weather gets bad. (E.g. Rain, thunderstorms). They will do that only when they are looking for Aiden Pearce after losing sight of him.
- It is unknown why during or after finishing Act III, the police will shoot at Aiden even if he does nothing. This is possibly due to him gaining the reputation of a dangerous man, as T-Bone shows during Hope is a Sad Thing.
- Police were originally able to shoot through their windows according to a trailer, but this seemingly has been removed in the final version of the game, presumably to prevent making them much more brutal and difficult to escape. This removal does not affect Fixers as they still can fire through their windows.
- There were originally female officers according to old gameplay videos. However, the dispatcher (who relays information and assignments to the department,) is a female officer. Female Police officers make an appearance in Watch Dogs 2.
- If Aiden dies while he was driving a police car and spawns near it, the same police car can then be seen on the map as a random police vehicle (flashing red and blue diamond). Reentering will remove the icon from the map. This happens during an online match.
- If Aiden hits an unoccupied police car, it reacts as it would if a police officer was inside (check quotes above).
- Police roadblocks seem to disappear after a few seconds unless the player is close to it.
- The Police can respond to shootings which may happen at any criminal convoy or gang hideout provided the criminals may not call enemy reinforcements. However, this will not work as the Police Heat level will be disabled if the enemy's reinforcements have been called.
- The Police may shoot and kill criminals on sight. However, this can easily be done if Aiden is hidden from the police's sight, otherwise, this will not work (They will mostly ignore criminals and shoot Aiden instead. For more, scroll up to Behavior section). This is obviously a Police priority A.I bug.
- The Police will not arrest any NPC under any circumstances even if they spot an armed criminal. This is widely considered to be a glitch.
- SWAT officers share the same dialogues with the regular police officers, although the Enforcers have additional dialogues.
- Upon arrival, SWAT Enforcers will often shout to the police "You girls can go home now; the cavalry's here."
