Off-duty cops in two counties in Alabama spent the weekend collecting saliva and blood samples from drivers at roadblocks.
According to Lt. Freddie Turrentine with the St. Clair County Sheriff’s Department, drivers were asked to voluntarily offer samples of their saliva and blood for a study being conducted by the Pacific Institute for Research and Evaluation.
The drivers were compensated for their samples.
“They’ve got big signs up that says ‘paid volunteer survey’ and if they want to participate they pull over there and they ask them questions and if they are willing to give them a mouth swab they give them $10 and if they are willing to give them a blood sample they give them $50. And if they don’t do anything they drive off,” Turrentine explained to The Daily Caller.
Turrentine said that St. Clair County had five roadblocks from Friday afternoon through the early morning hours of Sunday. He added that Bibb County also had roadblocks of this kind.
