His personal relationship with Tim Russert (one of the central witnesses to the case) cast doubt on his ability to impartialy judge the veracity of the witnesses and the testimony.
IF Wells knew that the juror knew Russert, he should be disbarred for allowing the juror to be seated uncontested.
If the defense team didn't know of that relationship, anything other than a thrown out verdict and a new trial would be immoral.
If a juror is personally acquainted with any of the parties or witnesses to a proceeding, isn't that juror required to disqualify himself, and aren't jurors informed of this requirement?
