Want a more realistic experience while playing LSPDFR? Download this and feel more immersed in your gameplay! This adds that background chatter that will really immerse you into the role of an officer! And the best of it all? You can create as many chatter lines as you want! No limitations.
 
Preview video (outdated, doesn't properly show what this plugin is capable of):
 
 
Features:
No external programs needed! Customizable volume for the chatter! It plays a random line of chatter between a custom time of  your choosing. Easy to setup, just drag and drop, then play! Easily create your own chatter lines! 35 different chatter lines by default!  
Setup:
The setup procedures are provided in the README.txt file.
It's really simple! In the ZIP file there's a folder called "Grand Theft Auto V", just drag the contents of this into your Grand Theft Auto V folder and you're all set!

Thanks to martinct for the awesome Dodge Charger model! On this model I made some slight adjustments: edited the car for city use (changed textures, removed some items on the car, etc.). 
How to install:
- Open up OpenIV, then click on Grand Theft Auto V.
- Navigate to: update/x64/dlcpacks/patchday4ng/dlc.rpf/x64/levels/gta5/vehicles.rpf
- Once you're there, drag in the files provided. If police2 files already exists there, just replace them.
- Rebuild and launch your game!
