Professor Eugene Volokh had an interesting little piece in his Washington Post column:

A footnote I’ve found in three recent Tennessee Court of Criminal Appeals cases, where Judge John Everett Williams was on the panel (e.g., State v. Wilson):

We acknowledge that we do not use titles when referring to every witness. We intend no disrespect in doing so. Judge John Everett Williams believes that referring to witnesses without proper titles is disrespectful even though none is intended. He would prefer that every adult witness be referred to as Mr. or Mrs. or by his or her proper title.

Good for Judge John Everett Williams!!!!!
