If they could drive her to a jail to give her a second breathalyzer, they could easily have driven her to a hospital and gotten either a blood or urine test.
The court has said that since she chose one of her options and was unable to perform it, that is not a refusal
Unless she subsequently agreed to another form of test, she's done. The cops can't force another form of test - yet. Look for laws to close this "loophole".
Or they simply could have let her go to the hospital where she would have had a blood test done anyways since she was the driver of a vehicle involved in an accident. But they didn't allow that to happen.
They have to perform the test within two hours.
That means drive to the hospital, find the evidence certified Nurse to take the blood.
It also means the delay can be used against the prosecution.
Was the booze going INTO her bood stream or was the booze on its way out? Picture a curve.
You could dring 4 shoots right now, take a blood test immediatly and the booze has not reached your blood stream. You would not be impaired for the first few minuts despite your consumption.
