Final answer:
The option not considered a reactive strategy for dealing with pretrial publicity is the expansion of jury selection, as it is a proactive strategy aimed at enlarging the jury pool.
Step-by-step explanation:
The reactive strategy for dealing with pretrial publicity that is NOT mentioned is the expansion of jury selection. Reactive strategies are actions taken in response to the potential or actual effects of pretrial publicity once a trial is imminent or underway. The options provided that are considered reactive strategies include issuing restrictive and protective orders, such as gag orders to prevent those involved in the case from making public statements; the sequestering of jurors to limit their exposure to media and outside information; and granting of trial continuances to allow public interest and media attention to decrease before the trial commences. Expansion of jury selection is more of a proactive strategy that involves enlarging the pool of potential jurors to find those who may not have been exposed or influenced by the pretrial publicity.
