Friday's edition of Danas has an interview (translated from Der Spiegel) with ICTY judge Wolfgang Schomburg. He has criticisms of ICTY's work, complaining, for example, about "...shaky indictments. One gets the impression that first they issue an arrest warrant, and only then start the real investigation." He also has reservations about uneven sentencing, about the control of information by the prosecutors, and about the public engagement of the ICTY prosecutor Carla Del Ponte.
This is my summary, with a little translation into English of their translation from the German. The Danas article can be found at their web site (click "Dijalog" on the menu). Or if you read German (sorry to say that I do not), you can find the entire interview in Spiegel.
