He doesn't think it's a good idea. But he doesn't know how to turn it off... the "tweeter." (The tweeter? Cue Tina Turner.)
"Judges wear black robes so that they will resist the temptation to publicize themselves, because we really speak for the law. And that is to be anonymous."
This is why I wouldn't want to be a judge. They're supposed to submerge their individuality and self-expression. They're supposed to become neutral expositors of The Law. Of course, they don't, not entirely, and everyone wants to figure out what they really are like, underneath that judge costume. But we only want to know because we need to understand and predict their opinions, and not because we'd be interested in their opinions if they didn't have the judicial power.
Oh, maybe for some of them we would, but as long as they are judges, engaged in the pretense of anonymity, they don't display much or any interestingness apart from the wielding of power.
Would you want to be interesting largely or solely because of the power you wield? It's nothing you've created, and if you weren't sitting there, in that seat of power, someone else would be, and then they would be all that you now are. What difference then does it make whether it's you or someone else?
