Another factor is that if the DOJ/FBI/CIA is taken down all at once all the currently incarcerated federal prisoners will be filing wrongful prosecution lawsuits en masse. Fucking lawyers will be licking their chops for a piece of the action.
There are hard core criminals who should actually be where they are whose fate will be decided by federal judges. Seen that movie before.
I can't see this getting straightened out without a military intervention. Tribunals until the scum is strained off and the good agents are reassigned. I think evidence of SC corruption could trigger this.
