I agree with everything you wrote in that comment! Other countries imprison their ex-leaders with some regularity. What the political result might be if we did that here, I have no idea. Some questions are unanswerable. Either an approach is tried, and we get to find out the result, or the untried approach just... disappears. Kind of like evolution. A mutation happens and some offspring "try it out". If they survive, the mutation persists. If not, there is nothing to be remembered.
