The Supreme Court’s main strength lies in adjudicating disputes based on things that have already happened. It is less good at predicting the future.

On Wednesday, for instance, it shut down plans to broadcast the same-sex marriage trial in San Francisco partly for fear that witnesses in the case would be harassed if their public testimony were made more public. That conclusion is known in the trade as speculation.

Consider first of all that we are talking about a trial held in open court and subject to intense press coverage. The witnesses are mostly paid experts whose views on the subject are already well known. “They’re not, after all, in the witness protection program testifying against Mafia bosses,” Eva Rodriguez wrote in The Washington Post.

Then add to the analysis that the additional coverage the court forbade was only closed-circuit transmissions to a few other federal courthouses around the country. (There had been talk of posting video on YouTube, but the idea was never approved and so was not before the Supreme Court.)
