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 his gun out in public, kills someone, runs over a civilian, steals a car (without the Disable Alarm hack), etc., the civilians can report him to police. After the phone report, a CTOS Scan will find Aiden's whereabouts. If Aiden fails to either stop the caller or fails to escape the CTOS scan, the police will respond immediately and arrive within a few seconds after the Scan, and apprehend Aiden (shoot to kill if more than one Heat Level or after Act III).
If a criminal shoots his 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 arrest/shoot him instead, unless the criminal is on their path. In other words, if a criminal pulls out a gun and/or shoots directly at the police, they will immediately respond by attacking back. The police usually do not shoot gangsters or mission enemies who attack Aiden, provided he is on their sight.
For example, the police will prioritize shooting at Aiden over the gangsters or mission enemies. If, however, the attackers are directly attacking the police, police respond by attacking back, provided Aiden is not in sight of the police. Police will become hostile if the player hits their squad cars, but if a civilian's car bumps into an occupied patrol car, they will not respond.
The Police A.I. seem to have a priority system. If a criminal has killed several police personel, Aiden's heat level may be increased, and if a helicopter is summoned, the marksman will open fire at the criminal if he opens 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 and shoot them. Another aspect which can be noticed very easily is that if the criminals are kept in a short distance against the Police, and Aiden is kept a long distance from between them, the police may still open fire at Aiden, ignoring the criminals in process. This can be interrupted by either hiding in an object (less effective option) or if the criminals begin shooting at a policeman (more effective option), which will temporarily attract all police attention to the criminals. Sometimes, if the Police spots a Criminal being visible armed, they will not put any effort to arrest/shoot him and will completely ignore him unless they are being attacked by him for some reason.
Strangely enough, police officers' accuracy on shooting against the criminal is worse than shooting against Aiden. That means, they often miss the targets as if the bullets do not register as damage against the criminal A.I. As a result, the police personel often get killed easily against the criminal's A.I. Police A.I. also "cheats" mostly on Search Mode. In the E3 version of the game, if Aiden evaded the police and they enter Search Mode they would just keep speeding around the map, wondering where he is on realism level. In the final version, however, this has been adjusted into more "cheaty" method, so 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 it knows. There are even many instances where the officers can get out of their cruisers and walk 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 if they don't know who the shooter is, and 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 the steam pipe hack is initiated against them. They will also respond and chase Aiden if he speeds, collides with a car or drives through a red light.
The Police Helicopter usually give chase during or after 3 heat level, depending the ACT. However, the Police Helicopter is also granted an unfair advantage. It can outrun even the fastest of cars and the sniper A.I. rarely misses shots. To overcome this, make constant drifts with a vehicle to lower the sniper's precision. In addition, the player can kill the sharpshooter (but this makes matters worse as the player gains more Heat) or disable the helicopter using the Disable Helicopter Hacking skill for a temporary disable or shoot it with the Destroyer to make it flee. Criminals may also open fire at the helicopter and in response, the marksman will attack back at the criminals.
They are much more powerful than regular police officers, carrying better weapons than regular officers and boasting better accuracy. Thanks to their body armor, they are able to take more damage than regular police. Elites also have helmets, but they are functionally useless as they still are 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, hence replacing the regular police SUVs roadblocks. Like the CPD, they will attempt to run the player off the road. Their roadblocks do not appear on Bad Blood, however.
Each SWAT SUV contains one Elite and one Enforcer sometimes there will be two Elites or three Elites. The Enforcer is always the driver, when on-foot, the Elites will take cover, but the Enforcer will walk (slowly) at the player.
SWAT teams equip different set of weapons. Their Elites on the ground mostly 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 do not make any appearances in the campaign or on the streets, and only appear during a Police Pursuit.
Their appearances during pursuits are treated differently when playing as Aiden. Depending on the player's progress on the storyline, SWAT teams will be more frequently encountered at later stages of the storyline. During Act I, SWAT teams will only be dispatched at the highest heat level, but not as frequent as the regular police officers. However, as soon as the player completes Act I, they will instead making their occasional appearance during the fourth heat level. Once the player completes the first two story chapters, SWAT teams becomes more apparent. They will appear occasionally at the third heat level, and during the highest heat level, regular patrol vehicles will stop being dispatched and are replaced by SWAT SUVs, making the pursuit much more intense, although the local police on-foot will still attempt to stop the player.
On Bad Blood on the other hand, 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 free-roam mode. If there are two players shooting at the police at the same time, the Police A.I will focus on the player who has the highest heat level, ignoring the other player completely. 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 get 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 on a single player only, ignoring the others.
In Online Hacking or Online Tailing, if the invader opens fire, nobody will report him as shooter, thus no patrol car will be dispatched. If, however, the player who is getting invaded shoots, the civilians will report him and the police will respond to 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.

- "You think that's gonna stop me? Think again."
- "No more fooling around. It's time we got serious."

- (laughs) "Time's running out little man."

- "Apprehend him!"
- "Apprehend the suspect!"
- "Roger that"
- All police vehicles have "MP" labeled on their license plates, which stands for "Metropolitan Police".
- The livery for the department is a white paint scheme, with a blue strip 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 which have them feature a centrally placed emblem.
- The spike strips used by the Chicago PD differ from the fixed location spike strips. The police spike strips are yellow and black and are permanently active. They are usually placed right beside the roadblock cars.
- The Chicago Police Department rarely spawn 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 parked at any Police Station. Some patrol cars can be located parked at The Wards Police Station only.
- Only Police Cavales 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 atop of a police car is also considered a crime.
- Police will ignore you completely if you try to harass them like standing to them too long, honking at them too long, etc.
- Occasionally, WKZ TV will report Aiden on various TVs throughout the city. At this point, all pedestrians will recognize him and will call the police for him if they spot him.
- Even if Aiden steals a car, the civilian will always mention that he is armed with a gun instead of reporting it as a car theft.
- Usually the 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 at night times or when the weather gets bad. (E.g. Rain, thunderstorms). They will do that only when they are looking for Aiden Pearce after losing a visual of him.
- It is unknown why during or after finishing Act III, the police will shoot at Aiden even if he does nothing. 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 is unaffected to Fixers as they can shoot through their car's window.
- There were originally female officers according to old gameplay videos. This was removed apparently to avoid controversy. However, the main dispatcher is a female officer (the one who reports anything to the CPD). Female Police officers make appearance in Watch Dogs 2.
- If Aiden dies while at least he was driving a police car and spawns near it, the same police car can then be seen in 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 orthewise 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 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."
- Enforcers will boast about their body armor during combat: "This is top of the line body armor; you don't stand a chance."
- In Watch Dogs //n/ Dark Clouds, a detective drives a Crown Victoria as an undercover cop car. This is also a reference to the fact that the Vessel is based on a Crown Victoria.
- While yet to be seen in the games, it is mentioned in Watch Dogs: Dark Clouds that the police have patrol boats.
- In the Wii U version of Watch Dogs, the Police A.I seems to be more relaxed, not being as difficult to the player. Officers in patrol cars are only armed with Handguns and the Police Cavales do not make appearance, instead, they are replaced by Police Sonarus LXs.
- The Chicago Police Department Vessel appears in Watch Dogs 2's mission CyberDriver. Two of them are on the movie set and can be taken once the mission is complete.
