Sequestration is rare, and becoming less common, due to the expense and concerns about the impact on jury members. In most trials that last more than a single day, jurors are instead sent home for the night with instructions to isolate themselves from inappropriate influence until they return and the trial resumes. Sequestration is most commonly used in high-profile trials in which media coverage and public conversations about the case may be so ubiquitous that it is difficult for jurors to avoid. A judge also may order that a jury be sequestered to prevent others from tampering with them through undue persuasion, threats, or bribes. The trials of O.J. Simpson in 1995, George Zimmerman in 2013, Bill Cosby in 2017 were modern cases in which it was done, with the jury spending 265 days in sequestration in the Simpson case.
