This modification will change your police from American Cops to American Cops.
I have no readme at this stage.
Extract the files.
Open up your gta3.img in your models folder in your GTA SA directory. Replace lapd1.dff and lapd1.txd with the new ones. This will replace all the cops in Los Santos.
To replace the cops in other cities, do the same thing except do it for the other cities
sfpd1 - San Fierro
lvpd1 - Las Venturas
csher - County Sheriff
dsher - Desert Sheriff
