vladimir:

Unless you have some inside information that there is an army of Croats and Albanians in the dock waiting to be convicted.

Bull shit vladimir, by your own data there are 6 Croats whose trial is "ongoing" (and 2 have been transferred to national courts) vs. 9 (+8) Serbs. So there are proportionally more Croatian cases outstanding than Serb.

Regarding Kosovo, it is a well-known fact that when the number of people in a category drops below about 5, statistical tests become insufficiently powerful. In the case of Kosovo the expected numbers are small enough you can't really draw any conclusions.

Most economists teach a theoretical framework that has been shown to be fundamentally useless. -- James K. Galbraith
