2. Who is Affected By a Gag Order?
Gag orders are directed at both the defendant and prosecuting parties, the lawyers involved, the jurors, and any witnesses that may be testifying during the trial. These parties must adhere to the gag order as a way to restrict what information about the case may become available to media outlets in both civil and criminal cases. Court personnel who are in the courtroom during the trial are also typically expected to follow suit during a gag order."
All of the parties in a trial can be under a gag order.
The idea that gag orders are used only by prosecutors when they have no case, is simply ridiculous. It is your opinion, and not based on the actions in our legal system.
