Federal Rule of Criminal Procedure 21 (a) provides for the transfer of proceedings to another district if the judge is satisfied that there exists a prejudicial atmosphere. To meet the requirements for a transfer, the trial judge must determine that there exists so great a prejudice in favor of the prosecution or against the defendant that there is a reasonable likelihood the defendant cannot obtain a fair and impartial trial. In the famous 1966 Sam Sheppard case, (Sheppard v. Maxwell) the United States Supreme Court held that where there was a reasonable likelihood that the prejudicial news prior to trial will prevent a fair trial, the judge should continue the case until the threat abates, or transfer it to another county not so permeated with publicity. This doctrine has been annunciated in other cases.
