Will police across the country use catheters on suspected drunk drivers? How close are we to becoming a police state?

BOISE, Idaho – When police officer Darryll Dowell is on patrol in the southwestern Idaho city of Nampa, he'll pull up at a stoplight and usually start casing the vehicle. Nowadays, his eyes will also focus on the driver's arms, as he tries to search for a plump, bouncy vein. "I was looking at people's arms and hands, thinking, 'I could draw from that,'" Dowell said. It's all part of training he and a select cadre of officers in Idaho and Texas have received in recent months to draw blood from those suspected of drunken or drugged driving. The federal program's aim is to determine if blood draws by cops can be an effective tool against drunk drivers and aid in their prosecution.
If the results seem promising after a year or two, the National Highway Traffic Safety Administration will encourage police nationwide to undergo similar training.
For years, defense attorneys in Idaho advised clients to always refuse breath tests, Ada County Deputy Prosecutor Christine Starr said. When the state toughened the penalties for refusing the tests a few years ago, the problem lessened, but it's still the main reason that drunk driving cases go to trial in the Boise region, Starr said.
The nation's highest court ruled in 1966 that police could have blood tests forcibly done on a drunk driving suspect without a warrant, as long as the draw was based on a reasonable suspicion that a suspect was intoxicated, that it was done after an arrest and carried out in a medically approved manner.
The practice of cops drawing blood, implemented first in 1995 in Arizona, has also raised concerns about safety and the credibility of the evidence.
"I would imagine that a lot of people would be wary of having their blood drawn by an officer on the hood of their police vehicle," said Steve Oberman, chair of the National Association of Criminal Defense Lawyers' DUI Committee.
