Mass murder on Ovčara is one oh the most terrible crimes which happened to the newly created Croatia on its way of gaining sovereignty. Carefully planned operation was conducted in couple of phases and the victims were wounded and medical personnel from the Vukovar hospital. Few of the survivors, guardians of the truth from the Grabovo had been spreading their story across Croatia, a story that had reached Tadeusz Mazowiecki, who sent team of experts to Grabovo. International community as a witness of that terrible crime did nothing. Also, under its recognizable blue helmets, the international community still was not taking any significant actions. Moreover, numerous crimes against civilians were committed before the eyes of International community, the most terrible of which is Srebrenica. The gravesite was discovered and exumed, the names of the perpetrators had been known and the international community still wasn't taking any significant actions. In the years to come international community had started taking some actions in sanctioning perpetrators, but the question is for what purpose and whether the sentence is proportionate to the crime. If we were to analyze the time Šljivančanin spent in prison, we'd come to the conclusion that for every person killed on Ovčara he received (by command responsibility) a sentence of twelve days. Is that punishment proportionated to the crime? Has the international community given its maximum? Has the international community been giving enough during these past thirty years to sanction perpetrators for mentioned crimes?
