Her driving was impaired by medication. It doesn't matter whether she drank alcohol or not - it doesn't matter that the businessman *thought* she drank alcohol.
He witnessed her, clearly impaired before and after she got in a car with her FOUR YEAR OLD.
She could have called a taxi, her husband, a friend - no.
She chose to drive.
I hope they throw the book at her for trying to make this about alcohol when clearly it's about her impaired driving.
Read the DUI laws- you don't have to be 'drunk' to be impaired.
