There are multiple "task force" cars in the st. charles area. These officers are NOT friendly but are generally looking for more serious problems such as drugs, etc… but also look for certain speeders, racers, and other lawbreakers. They wear plainclothes and have unmarked plates. Some of the cars are: tan taurus, black bmw, blue caprice, white caprice, black caprice, blue caprice, purple car with a black racing stipe…. there are more in the area, feel free to add
