Absolutely.
That's why you should make decisions about things like driving before you get into that condition.
It seems to me that in this situation, the cops are more at fault than the friend. Unless perhaps they explicitly told him to take the drunk home rather than back to his car.
You have a point there.
I remember a friend of ours getting too drunk to drive, we took his car keys....... the Ba..... had a spare set, sometimes there is nothing you can do against stupidity.
