Sad thing is that he is the cause of the death of the other driver. Jenner hit her from behind and pushed her into oncoming traffic where she was nailed by the Hummer. Sounds like Jenner is trying to blame it on the photogs but I'm not buying it.
As far as his personal choices go, who cares. If he would rather have girl parts and live as a woman, more power to him. Although, something tells me this isn't the last time the words "Jenner", "rear-ended" and "hummer" will be used in the same sentence.
