The article is about a recent violation of civil liberties in Colorado:

"Motorists in Colorado are expressing outrage over a weekend stunt in Gilpin County, about an hour's drive west of Denver, where highway checkpoints were set up so a private organization could ask for samples of blood and saliva."

"Sgt. Bob Enney said the deputies' assistance to the organization involved stopping motorists at the sites along Colorado Highway 119 for "surveys" on any drug or alcohol use. Surveyors also requested that motorists submit to breath, blood and saliva tests."
