My guess is they want to get the financial crimes moved to federal court so that he can serve some time and then get pardoned, since Poot has connections with Biden. If he is charged in the state then a pardon never happens because SC is a red state and they are not pardoning a democrat, or doing a favor for Dick, who is a democrat. If the rolls and parties were reversed then it would work the same way. In short, they obviously think he won’t spend a ton of time in jail if the only charges are related to the financial crimes.
The murder charges are the ones that would keep him behind bars the rest of his life, so those are the ones they have to beat. I would be really surprised if someone at that courthouse was not doing everything by the book given the profile of the trial and who was involved.
