Based on modifications to the POLICE PURSUIT SYSTEM PLUS Harder, and integrated several optional files from POLICE PURSUIT SYSTEM PLUS:

• Integrated the "Hidden Police Indicator Module (remove cop icons)" and the "Increase Police View Distance (Level 3)"
  

• (For UNITE MOD) You can find the fix for the undercover Crown Victoria and state police Dodge Charger's police light error caused by UNITE, as well as the issue with the state police Corvette having black paint in the optional file
  

This mod includes the Chicago police car livery and Illinois State Police car livery without the need for separate downloads

• If you don't want Chicago PD livery, you can download Lake Shore PD livery in optional file
