No, he needs to:
1. Keep everyone for an unspecified period.
2. Give some amnesty to a few trusted people, if any.
3. Prosecute as many as possible.
4. After all witness are no longer need, fire the employees that are not convicted or tried, keeping the trustworthy, if any.
5. Rebuild whatever needs to be rebuilt.
