As John Steele notes, Judge Posner inserted the photos below in a recent opinion in order to ridicule a lawyer for failing to cite what Judge Posner believed to be controlling precedent. My own view is that Judge Posner was unnecessarily harsh.
But if it is appropriate to use photos to ridicule lawyers for making mistakes, it seems to me that judges should be subject to the same kind of criticism. For example, as I note in the comments to John's post, Judge Posner makes a fairly basic legal mistake in the very same opinion described above. Namely, Judge Posner incorrectly describes forum non conveniens as a doctrine for "transferring" cases when, in fact, the doctrine is used to achieve a dismissal. Federal courts have no authority to transfer cases to other countries.
I suppose we could ridicule Judge Posner for this mistake. (If so, what photo would be appropriate to highlight the problem of judicial carelessness?) But I think that the law is sufficiently complicated that even the brightest lawyers and judges can make mistakes. If the mistake is severe, it can be the basis for a sanction, discipline, or malpractice action. But otherwise, it seems unnecessary to ridicule a lawyer (or a judge) for errors of the sort that the lawyer (or Judge Posner) made in this particular case. What's your view?
