The article clearly states AFTER the arrest has been made. The suspect is already detained and restrained. And the arresting officer would need probable cause for arrest. I think the point is being missed. If your piss drunk and are already arrested it simply means that an officer can take the sample instead of having to take you to the hospital to have the procedure done causing more cost and time in the hospital. Your not going to have needle wielding officers taking blood on suspicion of drunk driving, this would be administered long after you fell on your ass trying to pass a field sobriety test.
