Bloomberg View editorializes about South Africa's refusal to detain Sudanese President al-Bashir for whom an arrest warrant for war crimes and genocide is outstanding from the International Criminal Court. In South Africa's defense, it is possible they agreed not to detain him as a pre condition of his attending the African Union summit.
An argument can be made that it was important for him to be present. Not that South Africa could be bothered. It seems most of Africa's leaders would rather not be subject to a court in Europe, however diverse its staff and judges.
Given colonialism their feelings aren't surprising, however they are unfortunate. Africa is a continent that could use a large dose of law-abiding leadership a la Mandela.
