That's when I turned it off. I thought that was just too stupid. Even if they did explain why a cop would assume that a person in a car accident was drunk and why he didn't take that unconscious person to a hospital, the fact that the woman didn't raise a stink over it bothered me. I think the normal reaction of that person would be, "I was in a car accident and you threw me in jail?! What the @#$%!&* is wrong with you?!"
She did have one or more stiff drinks at the mayor's house right before leaving. I assumed that the cop smelled it on her breath, and saw no other reason for the crash.
As for not raising a fuss, I think it was very much a "well, this day has been excessively weird so far, waking up in the drunk tank is pretty much par for the course by now".
