ICC vs Omar al Bashir Case

South Africa made a reasonable decision by allowing Omar al Bashir to leave the country in contradiction with the ICC's order to have him arrested. Perhaps the South African government could not brush off the possibility of a diplomatic dilemma with other African countries. They couldn't subject themselves to the wrath of heads of African nations and risk being labelled a puppet of the west and ICC. My understanding is that Omar al Bashir committed his crimes in Sudan rendering it impractical for him to be arrested in South Africa. Besides the arrest was going to jeopardize the peace keeping activities in Sudan where South Africa is playing a key role. I would like to submit that the ICC's justice system is selective. There are so many African leaders who have committed crimes against humanity but they were not brought to book. 20 000+ people were massacred in Matabeleland and Midlands in Zimbabwe but nothing was done, Idi Amin never paid for his crimes, the list is endless. The truth is that the ICC has lost its relevance and has in some way become a western tool to fix hostile regimes whilst on the other hand the same court can not arrest them.
