Jury sequestration

Jury sequestration is the isolation of a jury to avoid accidental or deliberate tainting. Although sequestration is rare, publicity surrounding a trial and interested parties may interfere with juror objectivity; a judge may order that a jury be sequestered in order to prevent others from tampering with members of the jury through undue persuasion, threats, or bribes. This occurred most notably during the O.J. Simpson trial.
