As for LRM's choice of a jury trial, I'm sure his choice is self-interested, like everything else. It's not about his "trust" but more about his own personal advantage.
We all know from LRM's interviews and online ramblings, that he is arrogant and self-regarding and probably thinks he can manipulate and outsmart a juror of average citizens better than a judge.
