The reason why they are dragging their feet instead of appointing a special prosecutor for fabricated indictments

Messing up prosecution reform → Special prosecutor for fabricated indictments
vs
Special prosecutor for fabricated indictments first → Messing up prosecution reform
They have to go with the former, like they are doing now, to seize prosecutorial power and be able to withdraw indictments.
It would be ridiculous if they did it in the reverse order.
Once the organizational restructuring of the Serious Crime Investigation Agency and the Prosecution Office, the head of the Serious Crime Investigation Agency, and the personnel organization are all fixed, they will likely appoint a special prosecutor.
