Ok. So this smells funny.
First they said he refused to take a breathalyzer.
Then they said he blew a 0.00.
Then he said it was prescription drugs.
I saw the dashcam video. The unsteadiness, the wobbling, the struggling for words, the slurring... That just doesn't look to me like anything but drunk. And the arresting officers said he smelled of booze.
Is it possible they're covering for him?
