JakeS:

he arbitrarily classifies 7 of the Serbian suspects as being related to Kosova

The classification needn't be arbitrary. In wikipedia's List of indictees of the International Criminal Tribunal for the former Yugoslavia each indictee is assigned an ethnic group and an incident.

One thing that Vladimir does wrong is compare Indictees to Convictions, implying that those not convicted have been acquitted. This is not the case. The proper comparison would be the ratio of convictions to acquittals/case-dismissals as there are a number of cases which are ongoing, have been transferred to national jurisdiction, were never concluded because the indictee died, or in which the indictee is at large. Vladimir posted the full stats
here (these do not distinguish between the different wars or regions, only ethnic groups):
