One potential juror who was considered for a civil trial in Montgomery County on Wednesday morning could have brought a lot to the jury room. He’s the chief justice of the United States.

John G. Roberts Jr. showed up for jury duty in Rockville like other civic-minded citizens and was being considered for a civil trial in a case involving a car crash. He answered two questions in open court about relatives — noting that his sister in Indiana is a nurse, and his brother-in-law was with Indiana State Police — but none about his own line of work, which would be listed on a questionnaire. He then talked with attorneys and the judge privately at the bench.

Roberts was not selected, and left court without comment.
