Sorry, but Fani Willis is overreaching

17. Mary Trump has offerred the opinion that his personality will collapse at some point in the process with the possible

side effect that his health may do so too. If he loses enough of what props up his ego ($$$$$), or can no longer negotiate the outcome of one of the trials, or gets incarcerated to where he has no contact with anyone other than his lawyers, then he might rapidly decline.
According to her he lives in and on substantial denial. When he cannot deny his situation or get someone else to do it for him will be the point where he begins to fall apart.

IMO he should have been rendered incommunicado before this as a security threat to the nation. They did that with Noriega and others on the basis that they knew national secrets which might become public or transmitted to a 3rd party.
