PBS: Police are now taking roadside blood samples to catch impaired drivers by
It was about 6:30 on a Friday night in January when Phoenix Police Det. Kemp Layden pulled over a white Jeep Cherokee that was speeding and weaving in and out of its lane….A DUI police van equipped with a special chair and table for blood testing pulled up. The man refused to submit to a blood draw. So Layden grabbed his laptop and filled out an electronic warrant, or e-warrant, which was transmitted directly to a judge. Within 10 minutes, Layden had a search warrant. Another officer drew the man’s blood. A lab report later confirmed he had active THC and a sedative in his blood.
