Giving booze to someone underage is part of it but... tbh I didn't hear any details of 'assault'.
Did Brown know how old she was, that she was eighteen not nineteen? Was it his responsibility to find out? They were at a night club. Shouldn't the night club have verified ages? In the case of the first girl they met at a bar and there's no suggestion he plied her with alcohol. Shouldn't the bar have verified her age?
I thought that statement, from the story, was infantalizing. "He and others gave me alcohol".
Sorry? Did they hold you down and shove it down your throat? No? Oh, so you decided to drink on your own as an adult to the point you were 'very drunk'.
