"It's not our job to educate the public. Our job is to decide vitally important cases under the Constitution."

That's how Chief Justice John Roberts answered a high school student who asked him about televising Supreme Court arguments and — the WaPo summary implies — suggested that it would be a good thing because it would educate the public. I have follow-up questions: Is it your job to deprive the public of useful, nonconfidential speech that you generate in the course of doing your job? If that deprivation is not your job, why are you doing it? If you, in fact, do many things that are not your job — like answering questions from high school students — why are you in this one case relying on the argument that something is not your job?
