No. It is not about DSK. This is a story from the U.K. and it concerns “O Bummer”. The news article that I read actually starts off with “O bummer” (at least it did that in my reader) and then talks about a traffic fine because the US embassy refused to, or has failed to pay a “congestion tax”.
The real meat in this story is the failure of the US Embassy staff in London by racking up millions of dollars of traffic fines and not paying them. I am assuming that they think that they have diplomatic immunity and that they can do as they please in London.
