I've had this idea for a while that LCPDFR should group the callouts. (I'm going to jack your thread a little bit, but it's related and the suggestion section is not activated yet).
Basically, we define a key in the game to toggle what unit you are, sample categories could be metro/patrol, traffic/highway patrol, ESU/tactical/noose, all callouts, and maybe vice. Each category would have callouts assigned to it but selected "randomly":
Metro/patrol: would get the domestic violence, fights, public intoxication
traffic/highway patrol: speeding, DUI, street racing, motor vehicle accidents (if they can be coded up)
ESU/Tactical/Noose: high risk warrants (you could have to collect weapons or drugs throughout the house), bank robbery, hostage, shootout
Vice: prostitutes, (this category could be expanded if it could be coded: underground fight club, gambling rings)
all: obvious...
This would help out with role playing and if I feel like only doing traffic then I'm not bothered by domestic violence.
I wouldn't imagine this wouldn't be too difficult to implement though I've not see the code but I am a java and web programmer.
Again, sorry to jack your thread but I think this could help your Noose callouts.
