Being drunk doesn't absolve you of your crimes, it means you should stay sober if you don't live alone on the moon. Especially if you know you will act a certain way.
I hadn't heard of Scoble for years so I googled "scoble abuse", and the first result is something he supposedly wrote about being groomed and abused by his coach while he was a kid (http://archive.is/AN19H). Can't find the Facebook post this suggests was written by Robert and I don't know anything about the website it was posted on. But if it's true, then it gives you a way to trace back how Robert Scoble became an abuser. It also reflects on his substance abuse issues and if true shows that society fails to help victims and puts them on a path to become future perpetrators.
