Note: If you do not want the Good Cop rating to go down, take out your guns and wait for him to pretend to give up and fire at you once, so that you have a reason to kill him.

Escaping car enemies on missions
When you are supposed to flee from other cars shooting at you, look for big open spaces like the Staples Center parking lot and drive through them. The people chasing you will stay on the road and go all the way around, giving you a good chance to escape.

Blow up cars easily
Drive up behind a car and hold R to go into "bullet time". Then, aim at the license plate and fire. Most of the time it will take a single shot. For cargo trucks, aim under the passenger side and slightly to the back and fire. This makes stopping street racers and other people easy.

Stop carjackings
When your enemy is escaping by stealing a getaway car, kick them when they are pulling out the victim to stop them.

Spotting illegal drugs
To avoid wasting time frisking innocents, look for people that walk differently.

Restore health
Learn where the impound garages are located. When you get low on health, just visit the garage. You will not only get a fresh car, your health will be full again.

More damage
When an opponent is dazed, you can hit them hard into the wall with a finisher to do even more damage.

Deadly knife throw
In some situations when a enemy drops a knife, you can pick it and throw it. If thrown correctly, it will impale their forehead, killing them.

Increasing Cop rank
Go around checking everyone for drugs and weapons to get +1 Good Cop. Also, go to the Hancock Park area in the middle of the map. On a street corner at 2nd and Citrus Ave, you can frisk just about anyone close to or moving to the intersection and almost always finds drugs or weapons on them. Additionally, to increase your Good or Bad Cop rating easily, replay a stealth mission and choose your attack accordingly.

S.W.A.T. team
To get the S.W.A.T. team on you, kill a number of civilians (about thirty). The S.W.A.T. team will come after you in black vans.

Break fence
If you are stuck behind a fence that can be broken but do not have a car to break it with, Run at it and press X. This will cause you to dive through the fence, breaking it and freeing yourself.

Get past fence
When in a blocked off place with a fence on the other side, go up to it and face it. Do not press any buttons. The game will put you back on the other side within five seconds. It is easier to do this than hit the fence and not get through.

Movie reference
In the game, there is a sign that reads "True Crime: Streets Of L.A.: The Movie, Fall 2005".
