Story.
Quite frankly, I was surprised he was arrested for Intoxication Manslaughter in the first place. The blood tests revealed no alcohol in his system and only "traces" of marijuana. Since marijuana can stay in your system long after the effects wear off, there is no proof it had any impact on his "mental or physical faculties" (the law) at the time of driving.
Everybody can be outraged, but there simply was no case.
