I know its been asked, but I never saw an answer. I think it would be cool to have a dispatch system like Winterberg mod. I have the mod love the dispatch. 
Aren't you already the dispatcher in the game? I'm a POST certified Dispatcher and worked both Law and Fire at various points in my career. As a dispatcher, you find out from the Call Taker the type of incident, a few details, and location, and you decide what units to send.
In the game, you find out from the little dude in the corner the type of incident, a few details, and the location, and it's your job to decide what units to send. Do you call from off map? Do you use the units in the stations? Do you send an ALS engine and BLS ambulance for transport? Is it in an area where the Squad might get there first? Do you send both the squad and an ambulance to see who will get there first? Is it a fire and you don't want to deplete all of your station resources so you send a light force from FS1 but call for engines from off the map so something is still inside the station in case a call comes out next to it or far from the off-map entry point?
I've never played the Winterberg mod, but I don't see how pressing a button and having it make those decisions for you is worth having. The thing about the LA Mod and LA Emergency services in general is the flexibility that we have in responses. There are numerous units that are similar, but not the same. From ALS engines, to BLS engines, to USFS engine which is smaller and is more useful in the forested parts of the map, but has no deck gun.
In real life and the game, there is no "alarm system" for just that reason. If the Incident Commander wants 2 task forces and 6 rescue ambulances, that's what he'll call for.
For example I like that you already have it to where you aim the gun at them and the "Handcuffs icon" will appear, then they will kneel and get arrested that is an improvement. But what about additonal features such as if possible adding a command to "Compliance" where your officer will tell them to stop and put hands up and maybe a percentage chance that they will or they will run.
That is exactly how it works now. Sometimes they stop and comply, other times they just ignore the office and keep running. The improvement in the next version which I dont beleive was in the last, is that if the suspect is shooting at you, your only two choices are to pull your gun and return fire, or attempt to grab him without pulling your gun.
Police Cars with a "Pull over" command, when used on a vehicle that has suspect in it "carjacker, getaway etc" the command will make them get out of the car the same way the PD Helicopter makes them get out when they are being "Followed".
Any other improvements to make the game fun is a plus too!
Pull over and pursuit commands have already been discussed in this thread.
