I dont condone the drink driving however I am not that concerned with him being out having a few drinks providing he is doing the appropriate rehab, which I assume he is.
I have no problem with "a few" (definition no more than 3) either.
But this was evidently more than a few, and you don't need to be a brain surgeon to know that getting hammered is of no help to a rehabilitation process.
Was his reading 0.08 or thereabouts at 2 something am. If I am out at that time I would not be blowing that low. Based on that I assume he was taking it a little easy and not completely writing himself off like most would.
I understand that drinking is not the best for rehab however I doubt he is out on the piss 7 nights week so I doubt the 6 or 7 drinks he had will hurt.
