The ICTY has assigned a counsel to Karadzic. It is the British lawyer Richard Harvey.
Allthough a few newspapers reported it many leave out to mention that he previously served at the ICTY to defend two KLA suspects (Haradin Bala and Lahi Brahimaj: Brahimaj is still appealing his verdict). Doing this he made some remarks that were highly critical of Serbia and the way it conducted war. In addition he doesn't know a thing about Bosnia. The main way he can help Karadzic is with his knowledge of the rules of the court.
Of course a professional lawyer is supposed to be able to represent anyone. But that is the theory. Reality is that people tend to start to believe what they say. Psychologists call this effect cognitive dissonance and it can proved with psychological experiments where people are paid to defend a certain position. Add to this the effect that first impression count most and you have to conclude that Harvey will find it very difficult to talk about the Serb cause with the same sympathy that he once talked about the Albanian cause.
The ICTY defends itself by pointing out that Harvey is only a counsel and Karadzic will still be able to represent himself. But this is hard to maintain when one considers that the ICTY was not prepared to finance the lawyers that Karadzic had employed to help him. Harvey looks like an excuse lawyer whose mere presence harms his customer.
