First, I would like to say that yes, I am a
huge Billy Joel fan. In fact, a few days ago, we were talking about this incident at the dinner table, trying to explain to my FIL just who Billy was--and then I looked down and realized I was wearing one of my many Billy concert tees! I hadn't done so intentionally--it was just what I pulled out of the drawer that morning.
That being said, I have really been trying to look at the posts on this thread objectively. I do not automatically believe Billy is 100% innocent. He does have a problem with alcohol, and, as much as I admire him, I was very disturbed when I heard him on an interview after his rehab stint telling the reporter he "had no problem." Hmm, can you say "denial?" It ain't just a river in Egypt, my friend.
However, I think it is very wrong for people to assume he was drunk
the day of this incident because he has been in rehab. From what I understand, he does
not have a drunk driving record. He has been in three accidents, but he was never arrested for DWI or DUI. This doesn't mean he wasn't drunk; he could have been, for all we know. But, maybe the conditions were bad. Maybe he's a sucky driver.

The point is,
we don't know. It's just not fair to assume anything at this point, IMHO.
