When you reach 3 star wanted cops are starting shoot in driveby style.
SWAT, FBI and soldiers are doing it too.
It's simply cleo mod so put "cops_drive_by.cs" in your cleo folder.
I'm not writing very well in english so, pleas tell my if I wrote something wrong.
This can be real sh*t, man, better you upload your mod at another gta website, such as: www.gtainside.com, or www.gtagaming.com, and other, because in this website, they won't approve it!
