Does anybody know if any of the Serbs facing trial at the ICTY were charged by Serbian courts first?
Difficult question. "Facing trial at the ICTY" may include secret indictments (yes, they exist in Kangaroo Kourt)
Since ICTY statute allows double jeopardy, Kangaroo Kourt can pick any Serb already convicted.
Since Serbia is supposedly backward and undemocratic, it is interesting to compare what UN is doing to prosecute crimes committed by Kosovo Albanian extremists and subsequently to ask your question: Does anybody know if any of the Albanians facing trial at the ICTY were charged by UN courts in courts first?
