Again this all before his BAC will come back.. but yes I said buying time to speculate he was drunk.
Levels go down, how do you prove he was drunk at the scene?
Depends on if he was drinking with anyone. Witnesses can always say how many drinks they saw him drink, if he was drinking in a bar or with someone.
The TMZ article said he received medical treatment. Interesting he was willing to forego that for a while as he holed up in a house.
