No DNA was taken in the recent traffic stops in St. Clair County, according to the Maryland-based company that conducted the surveys.
During the past weekend, off-duty sheriff deputies took part in the voluntary survey. Some people complained about the blood samples and oral swabs there were taken.
John Lacey with Pacific Institute for Research and Evaluation said this was a voluntary program and no coercion was used. The information to determine if drivers were under the influence of alcohol or prescriptions drugs was kept anonymous.
"We were conducting a voluntary survey. Absolutely voluntary. There was no coercion involved and we are not looking for DNA or other such identifiers," Lacey said.
Lacey said he was surprised at the criticism of the survey program which began back in 1973.
Governor Robert Bentley has called for an investigation to see what and how the information would be used. Bentley questions if the civil rights of Alabamians were violated with the traffic stops.
Lacey doesn't expect the survey program to return to Alabama for another five or ten years.
