So maybe Tiger Woods had a big fight with his wife, got pissed off and went tearing off in the car and then had an accident. No alcohol was involved. Nobody got hurt but Tiger. So what?
Good grief, give it a rest already. Police investigations. If he didn't fail an alcohol test, end of conversation. STFU and move on.
By the way, the only thing you can really prove at all here is whether drugs or alcohol were involved. Again, if not, that's the end of this affair.
