This gamemode is the easiest of all, and for good reason. Its pretty standard.
Just kick down the door and arrest the bad guys. Easy.

In this gamemode there isnt alot to worry about, no threat no sweat.
Main threats include:
1. Armed suspects.

Armed suspects are pretty easy to deal with.
Bad guys with guns! Not a big threat in this mode.
More info in the ROE section.
2. Door traps.

Doors traps are trip-wire traps that can be found on the bottom of some doors, they can easily be disarmed by using the multi-tool. If the trap is on the other side of the door you can simple peek the door to disarm it. Always watch out for traps!

Also known as ROE.
1. if you see a suspect with a gun. Yell to make him drop the gun (press F while pointing at the suspect), if he does not comply after 5 yells, shoot him once, yell again. If he does not comply, kill him.
2. if you see a suspect pointing the gun, yell once. If he turns around, bang bang bang. hes dead.
3. if you see a suspect pointing a gun at the door thru the mirror gun, peek the door with a flashbang.
Then yell 10 times. If he does not comply, drop his ass.
4. if the guy is already shooting, dont hesitate.

Normally the objectives are simple, you just have to detain or kill anyone on scene.
Sometimes you have special objectives like, detaining a set amount of suspects,
or getting evidence. Pretty simple.

I dont have anymore guides at the moment, when i make another guide about gamemodes i will put the link here :D.
