The way Mr Botha is being treated is acutely sensitive. The authorities have been desperate to make sure they do not appear to be soft on him, nor vindictive.
It's now emerged that Mr Mandela personally tried to persuade Mr Botha to testify before the Truth and Reconciliation Commission and authorised substantial amounts in legal aid to help him do so. The news has caused fury in some quarters with one party, the Pan Africanist Congress, saying it is disgraceful that Mr Botha's treatment looks more generous than that accorded to the victims of human rights abuses during his time in office.
A senior lawyer said it was not sensitive to the new South Africa. But it shows just how desperate Mr Mandela has been to avoid what is now happening.
Having refused to answer the Commission's questions Mr Botha will now be prosecuted in an ordinary court of law.
