The usual approach is to demand a showing of actual prejudice. In the 1981 case of People v. Botham, the Colorado court overturned the defendant's murder conviction partly because there had been a denial of a change of venue. The court emphasized the number of jurors who had expressed an opinion that the defendant was guilty, the number who had been exposed to pretrial publicity, the juror's knowledge of the details of the crime, and the information that was brought forth on voir dire to find that the defendant met the burden of showing a presumption of partiality.
