I would like to just inform everyone so people do not get the wrong idea.
This is in no way a modded version / a special server / a hacked game / or edited scripting for GTA IV.It is just simply playing multilayer a certain way. And that certain way just happens to be using the in game emergency service vehicles to keep the city safe.
I do not want anyone to get the wrong impression, and think that i have a dedicated server that puts out calls for dispatch to send out.
I do not !!! 
>>>>Yet...
The calls come in from 3 places.
1 - The units on patrol
2 - Whatever dispatch
decides to put out Yes whoever is dispatcher in their head creates calls, officers make it what they want, unless something else is found, difficult to grasp i know, but you would have to see to understand it.
3 - Any humans acting like civilians that come across anything
Central may send you somewhere, and you may come across nothing. Other times you may just stumble across something. You never know. My suggestion to those who are curious and want positions is to come out for a ride along some night and see if it is for you.
For an example i was sent to a completely fake robbery at a gas station one night, when i got there the entire thing exploded ! and we had an MCI on our hands. so don't think it cant happen.

The civilian role is played by anyone who wants to be just that. Police will pull you over if they catch you doing anything wrong, if you get in an accident or are in need of assistance, they will respond to protect you.
however their are rules for civilians, No explosives, no emergency vehicles, no helicopters, and no airport access.
Civilians, can have up to $1,000 dollars in fines against their name at any time. Once they cross the 1000 dollar line, a warrant is issued for their arrest.
Civilians - May pay fines by arranging a time to meet with the issuing officer after the fines have been issued.
Civilians may have up to 2 arrests before they are considered prison material. 3rd times the charm.
so that's how we play involving a civilian, I just didnt want anyone to get the wrong impression. I will be releasing a mod at some point but it will only be for modified 360 consoles. And with that said, i am also waiting to see what they release as additional content in February before i even think of beta testing the mod...
If you are still interested i will be talking with you on the 26th to take your questions.
