Should lawyers be disciplined for criticism of judges?

Issues related to the freedom of speech of lawyers continue to hit the headlines.  A few days ago, I posted a comment on the on-going debate about whether an attorney should be disciplined for inappropriate and offensive comments about another lawyer.  I have also posted on the question as it relates to the limits on comments about judges (see here).  I am writing about that second question again just to point out that A Public Defender has posted his own comments (here) on whether attorneys should be disciplined for criticizing judges.
