Character upgrades
As your rank gets better (5 being the worse, and 1 being best), you can buy better upgrades for your character at the Police Department Armory, such as better zoom for your guns, or a more slow-mo dive. You can also purchase new guns to use. The guns will be in the trunk of your police car that you get from the garage.
Defeating President Lincoln
When fighting President Lincoln makes sure that you have bought the tranquilizer gun at the police armory when you have reached the second rank. Stand in the room with all the thugs. Shoot out the window and zoom in on Lincoln across the scaffold. Shoot him until he passes out. Then, interrogate him.
Driving skill ranks
Reach the indicated rank to have the corresponding weapons driving skills available in the police garage.
Go into a store, extort them, then come out. Walk back in and repeat as many times as desired to get more money.
Easy ranks
If you do not mind earning Bad Cop points, use the following trick to rank up detective levels easily. Go to a place where there are lots of people, such as Central Park. Frisk as many people as you can, plant evidence, and arrest them. You will get one Bad Cop point if you arrest them correctly. Also, you will get three career points every time you do so. It should only take about a half hour at the most to rank up a level.
Use the following trick to get easy arrests without Bad Cop points. Go into a car dealership or a dojo and frisk all the customers inside. All the customers will have something for you to take as evidence. Arrest them for extra career points.
For easy arrests, run and tackle people, then punch them about three times. Get off them and someone near or that person will start to fight with you. Knock them out and arrest them.
Faster shotgun reloading
When using a shotgun, slow reloading can be a big problem. When you start to reload a shotgun and just stand there, it is very slow. Start running around to reload almost three times as fast.
Fighting styles
If you are having trouble completing a fighting mission where you must fight thugs hand-to-hand, it is best to drive around to different Dojos when not on a mission to learn different fighting styles. Some styles are better used on some opponents than others. The best styles are Thai Boxing and Tae Kwon Do. They seem to be effective on a wider variety of opponents and can defeat more fighting styles than other ones. Also, do not overlook your default "Brawling" fighting moves as they can prove very effective against some of the fancier martial arts like Wushu. Switch between styles while in combat to find the best one for each situation. If you can score hits with combos of three or more moves on one opponent without them blocking any of your hits (or stunning them), then your style is better than theirs. Also, during the "fight club" mini-missions you can sometimes get a hint as to what styles your opponents are going to use by the little gestures and moves they make before the beginning of a match.
Get cops to stop shooting you
Sometimes, when you are in your street clothes and shoot at someone in front of a cop, the cop will start shooting at you. To get them to stop, simply turn towards them and flash your badge at them. They should then stop shooting at you.
Getting criminals to surrender
Enemies are more likely to surrender if you fire a warning shot from a gun larger than theirs. You can then proceed to arrest them without starting a gunfight. Note: This does not always work.

Grand Theft Auto reference
When you get the option to start driving taxi missions, Marcus comments that he cannot believe it and says "Next thing, I'll be flying remote control toys and shit." This is obviously a reference to all the RC car/plane/helicopter levels in the Grand Theft Auto series of games.
Keep car door open after you jump out
When you jump out you will find that your door is stuck. To keep it open, get in on the passenger side.
Kill without filling the Rouge meter
Kill a group of people to fill your Rogue meter. Once the cops come after you, let them kill you. After you are put you on street patrol, leave the station. Enable the "Super Cop" code, and you can now kill as much as you desired without your Rogue meter filing.
Level select
Pause game play and enter the CompStat/Map screen. Then, hold [Shift] + F and press [Enter] three times.
Lower Rogue meter
To allow your rogue meter to cool down, just enter any subway station. Cops will not follow you down and you will be safe.
Neutralizing criminals
To neutralize a criminal person that is running, take out your stun gun and use it until his or her health is gone. You can then arrest him or her.
No motorcycle wrecks
Pop a wheelie and do not stop. Cars will not make you fall off or slow down much.
Provoke citizens to fight you
This is a very good way to clean up all precincts quickly, without getting a Bad Cop rating. Get in a car and ram into another car that someone is driving. The driver will get out of their car angry and start provoking you while throwing a big fit. Get out of your car while they are still throwing a fit and wait until you see a health bar over their head. You can now beat them down and arrest them for a quick and easy three Good Cop and three Career points. You can repeat this until you clean up the area.
Recommended vehicles
The best vehicles to use at Detective Rank 2 is the 5.4L SC V8 coupe; and at Detective Rank 4 the 6.0L V8 coupe. If you use the 6.0L coupe, make sure to take it to a garage and get a street upgrade. Also, if you find one of the bullion vans driving around, hijack one. These will push any car out of the way, and in one hit you can sometimes put a car on black smoke. If you are stuck on the last driving arena mission (one lap around Central Park), just keep hitting her car in this truck to get her stuck for an easy win. The only problem with this vehicle is cornering. Do not be afraid to use this vehicle like a rhino.
Redman Gone Wild mini-game: More time
An easy way to get more time is to kill people. It is impossible to complete it by just driving. You must get out and shoot them.
Reload stun gun
Commandeer any police cruiser, open the trunk, and you can then reload your stun gun. This can be done repeatedly whenever the gun is low or empty.
Reloading
There are two ways to reload your ammunition. The first is by accessing the trunk of any car that you own. This also gives you access to your personal armory. The other way is to get a police car then access its truck. Using the police car will refill all your weapons but will not give you access to your personal armory.
Sour Candy mission: Easy completion
In the Palermo mission "Sour Candy", follow Candy up the climbing wall to the track. Instead of starting the race, go in the opposite direction. For the first two sets of hurdles, break the ones in the center lane by running into them. Then, break the last two sets of hurdles on the inside lane of the track. This will allow you to run in the race and not have to jump. Candy will be forced to jump over the hurdles slowing her down, so you can catch her more easily.
Taking out key suspects
To disarm key suspects easier without killing them, raise your Detective level by solving street crimes to unlock the Taser pistol and Tranquilizer rifle (found in police station's basement armory). These work well for safely capturing key suspects without killing them accidentally, and is much easier than trying to get an aim on their arms or legs for a "neutralizing shot".
