Off-duty St. Clair County deputies stopped cars at random at road block areas. The road blocks were marked with signs stating it was a paid survey. Cars stopped were asked for voluntary cooperation. Drivers were offered $10 for a mouth swab, and $50 for a blood test. If they refused, they were free to drive away.
